+   * "last chance" anti-recursion protection is triggered when the recursion

+     means the cleanup code has itself gone into an infinite loop, or the
+     RecursionError has been mistakingly ignored. When this protection is
+     triggered, the interpreter aborts with a Fatal Error.
+
+   In addition, the "overflowed" flag is automatically reset when the
+   recursion level drops below "current recursion limit - 50". This heuristic
+   is meant to ensure that the normal anti-recursion protection doesn't get
+   disabled too long.
+

+   A module that plans to do a blocking system call (or something else

+    Py_BEGIN_ALLOW_THREADS
+    ...blocking system call here...
+    Py_END_ALLOW_THREADS
+    ...interpret result here...
+
+   The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
+   {}-surrounded block.
+   To leave the block in the middle (e.g., with return), you must insert
+   a line containing Py_BLOCK_THREADS before the return, e.g.
+
+    if (...premature_exit...) {
+        Py_BLOCK_THREADS

+        PyErr_SetFromErrno(PyExc_IOError);
+        return NULL;

+    Py_UNBLOCK_THREADS
+
+   For convenience, that the value of 'errno' is restored across
+   Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
+
+   WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND

+

+/* This file defines dynamic annotations for use with dynamic analysis
+   tool such as valgrind, PIN, etc.
+
+   Dynamic annotation is a source code annotation that affects
+   the generated code (that is, the annotation is not a comment).
+   Each such annotation is attached to a particular
+   instruction and/or to a particular object (address) in the program.
+
+   The annotations that should be used by users are macros in all upper-case
+   (e.g., _Py_ANNOTATE_NEW_MEMORY).
+
+   Actual implementation of these macros may differ depending on the
+   dynamic analysis tool being used.
+
+   See http://code.google.com/p/data-race-test/  for more information.
+
+   This file supports the following dynamic analysis tools:
+   - None (DYNAMIC_ANNOTATIONS_ENABLED is not defined or zero).
+      Macros are defined empty.
+   - ThreadSanitizer, Helgrind, DRD (DYNAMIC_ANNOTATIONS_ENABLED is 1).
+      Macros are defined as calls to non-inlinable empty functions
+      that are intercepted by Valgrind. */

+     Annotations useful when implementing condition variables such as CondVar,

+     user-defined synchronization mechanisms.
+
+     The annotations _Py_ANNOTATE_HAPPENS_BEFORE() and
+     _Py_ANNOTATE_HAPPENS_AFTER() can be used to define happens-before arcs in
+     user-defined synchronization mechanisms: the race detector will infer an
+     arc from the former to the latter when they share the same argument
+     pointer.
+
+     Example 1 (reference counting):
+
+     void Unref() {
+       _Py_ANNOTATE_HAPPENS_BEFORE(&refcount_);
+       if (AtomicDecrementByOne(&refcount_) == 0) {
+         _Py_ANNOTATE_HAPPENS_AFTER(&refcount_);
+         delete this;
+       }
+     }
+
+     Example 2 (message queue):
+
+     void MyQueue::Put(Type *e) {
+       MutexLock lock(&mu_);
+       _Py_ANNOTATE_HAPPENS_BEFORE(e);

+       _Py_ANNOTATE_HAPPENS_AFTER(e);
+       return e;

+Functions and macros for modules that implement new object types.
+
+ - PyObject_New(type, typeobj) allocates memory for a new object of the given
+   type, and initializes part of it.  'type' must be the C structure type used
+   to represent the object, and 'typeobj' the address of the corresponding
+   type object.  Reference count and type pointer are filled in; the rest of
+   the bytes of the object are *undefined*!  The resulting expression type is
+   'type *'.  The size of the object is determined by the tp_basicsize field
+   of the type object.
+
+ - PyObject_NewVar(type, typeobj, n) is similar but allocates a variable-size
+   object with room for n items.  In addition to the refcount and type pointer
+   fields, this also fills in the ob_size field.
+
+ - PyObject_Del(op) releases the memory allocated for an object.  It does not
+   run a destructor -- it only frees the memory.  PyObject_Free is identical.
+
+ - PyObject_Init(op, typeobj) and PyObject_InitVar(op, typeobj, n) don't
+   allocate memory.  Instead of a 'type' parameter, they take a pointer to a
+   new object (allocated by an arbitrary allocator), and initialize its object
+   header fields.
+
+Note that objects created with PyObject_{New, NewVar} are allocated using the
+specialized Python allocator (implemented in obmalloc.c), if WITH_PYMALLOC is
+enabled.  In addition, a special debugging allocator is used if PYMALLOC_DEBUG
+is also #defined.
+
+In case a specific form of memory management is needed (for example, if you
+must use the platform malloc heap(s), or shared memory, or C++ local storage or
+operator new), you must first allocate the object with your custom allocator,
+then pass its pointer to PyObject_{Init, InitVar} for filling in its Python-
+specific fields:  reference count, type pointer, possibly others.  You should
+be aware that Python has no control over these objects because they don't
+cooperate with the Python memory manager.  Such objects may not be eligible
+for automatic garbage collection and you have to make sure that they are
+released accordingly whenever their destructor gets called (cf. the specific
+form of memory management you're using).
+
+Unless you have specific memory management requirements, use
+PyObject_{New, NewVar, Del}.

+
+/* Functions to call the same malloc/realloc/free as used by Python's
+   object allocator.  If WITH_PYMALLOC is enabled, these may differ from
+   the platform malloc/realloc/free.  The Python object allocator is
+   designed for fast, cache-conscious allocation of many "small" objects,
+   and with low hidden memory overhead.
+
+   PyObject_Malloc(0) returns a unique non-NULL pointer if possible.
+
+   PyObject_Realloc(NULL, n) acts like PyObject_Malloc(n).
+   PyObject_Realloc(p != NULL, 0) does not return  NULL, or free the memory
+   at p.
+
+   Returned pointers must be checked for NULL explicitly; no action is
+   performed on failure other than to return NULL (no warning it printed, no
+   exception is set, etc).
+
+   For allocating objects, use PyObject_{New, NewVar} instead whenever
+   possible.  The PyObject_{Malloc, Realloc, Free} family is exposed
+   so that you can exploit Python's small-block allocator for non-object
+   uses.  If you must use these routines to allocate object memory, make sure
+   the object gets initialized via PyObject_{Init, InitVar} after obtaining
+   the raw memory.

+ *       Define macros for handling SIGFPE.
+ *       Lee Busby, LLNL, November, 1996
+ *       busby1@llnl.gov
+ *
+ *********************************************
+ * Overview of the system for handling SIGFPE:
+ *
+ * This file (Include/pyfpe.h) defines a couple of "wrapper" macros for
+ * insertion into your Python C code of choice. Their proper use is
+ * discussed below. The file Python/pyfpe.c defines a pair of global
+ * variables PyFPE_jbuf and PyFPE_counter which are used by the signal
+ * handler for SIGFPE to decide if a particular exception was protected
+ * by the macros. The signal handler itself, and code for enabling the
+ * generation of SIGFPE in the first place, is in a (new) Python module
+ * named fpectl. This module is standard in every respect. It can be loaded
+ * either statically or dynamically as you choose, and like any other
+ * Python module, has no effect until you import it.
+ *
+ * In the general case, there are three steps toward handling SIGFPE in any
+ * Python code:
+ *
+ * 1) Add the *_PROTECT macros to your C code as required to protect
+ *    dangerous floating point sections.
+ *
+ * 2) Turn on the inclusion of the code by adding the ``--with-fpectl''
+ *    flag at the time you run configure.  If the fpectl or other modules
+ *    which use the *_PROTECT macros are to be dynamically loaded, be
+ *    sure they are compiled with WANT_SIGFPE_HANDLER defined.
+ *
+ * 3) When python is built and running, import fpectl, and execute
+ *    fpectl.turnon_sigfpe(). This sets up the signal handler and enables
+ *    generation of SIGFPE whenever an exception occurs. From this point
+ *    on, any properly trapped SIGFPE should result in the Python
+ *    FloatingPointError exception.
+ *
+ * Step 1 has been done already for the Python kernel code, and should be
+ * done soon for the NumPy array package.  Step 2 is usually done once at
+ * python install time. Python's behavior with respect to SIGFPE is not
+ * changed unless you also do step 3. Thus you can control this new
+ * facility at compile time, or run time, or both.
+ *
+ ********************************
+ * Using the macros in your code:
+ *
+ * static PyObject *foobar(PyObject *self,PyObject *args)
+ * {
+ *     ....
+ *     PyFPE_START_PROTECT("Error in foobar", return 0)
+ *     result = dangerous_op(somearg1, somearg2, ...);
+ *     PyFPE_END_PROTECT(result)
+ *     ....
+ * }
+ *
+ * If a floating point error occurs in dangerous_op, foobar returns 0 (NULL),
+ * after setting the associated value of the FloatingPointError exception to
+ * "Error in foobar". ``Dangerous_op'' can be a single operation, or a block
+ * of code, function calls, or any combination, so long as no alternate
+ * return is possible before the PyFPE_END_PROTECT macro is reached.
+ *
+ * The macros can only be used in a function context where an error return
+ * can be recognized as signaling a Python exception. (Generally, most
+ * functions that return a PyObject * will qualify.)
+ *
+ * Guido's original design suggestion for PyFPE_START_PROTECT and
+ * PyFPE_END_PROTECT had them open and close a local block, with a locally
+ * defined jmp_buf and jmp_buf pointer. This would allow recursive nesting
+ * of the macros. The Ansi C standard makes it clear that such local
+ * variables need to be declared with the "volatile" type qualifier to keep
+ * setjmp from corrupting their values. Some current implementations seem
+ * to be more restrictive. For example, the HPUX man page for setjmp says
+ *
+ *   Upon the return from a setjmp() call caused by a longjmp(), the
+ *   values of any non-static local variables belonging to the routine
+ *   from which setjmp() was called are undefined. Code which depends on
+ *   such values is not guaranteed to be portable.
+ *
+ * I therefore decided on a more limited form of nesting, using a counter
+ * variable (PyFPE_counter) to keep track of any recursion.  If an exception
+ * occurs in an ``inner'' pair of macros, the return will apparently
+ * come from the outermost level.
