Make fixes and improvements - Introduce __assert_disable global - Improve strsignal() thread safety - Make system call tracing thread safe - Fix SO_RCVTIMEO / SO_SNDTIMEO on Windows - Refactor DescribeFoo() functions into one place - Fix fork() on Windows when TLS and MAP_STACK exist - Round upwards in setsockopt(SO_RCVTIMEO) on Windows - Disable futexes on OpenBSD which seem extremely broken - Implement a better kludge for monotonic time on Windows 2022-06-25 18:17:31 -07:00			`#ifndef COSMOPOLITAN_LIBC_THREAD_OPENBSD_INTERNAL_H_`

Rewrite memory manager Actually Portable Executable now supports Android. Cosmo's old mmap code required a 47 bit address space. The new implementation is very agnostic and supports both smaller address spaces (e.g. embedded) and even modern 56-bit PML5T paging for x86 which finally came true on Zen4 Threadripper Cosmopolitan no longer requires UNIX systems to observe the Windows 64kb granularity; i.e. sysconf(_SC_PAGE_SIZE) will now report the host native page size. This fixes a longstanding POSIX conformance issue, concerning file mappings that overlap the end of file. Other aspects of conformance have been improved too, such as the subtleties of address assignment and and the various subtleties surrounding MAP_FIXED and MAP_FIXED_NOREPLACE On Windows, mappings larger than 100 megabytes won't be broken down into thousands of independent 64kb mappings. Support for MAP_STACK is removed by this change; please use NewCosmoStack() instead. Stack overflow avoidance is now being implemented using the POSIX thread APIs. Please use GetStackBottom() and GetStackAddr(), instead of the old error-prone GetStackAddr() and HaveStackMemory() APIs which are removed. 2024-06-20 20:46:42 -07:00			`_Atomic(int) *tf_tid;`
