wait4() is now solid enough to run `make -j100` on Windows. You can now use MSG_DONTWAIT on Windows. There was a handle leak in accept() that's been fixed. Our WIN32 overlapped i/o code has been simplified. Priority class now inherits into subprocesses, so the verynice command will work and the signal mask will now be inherited by execve() and posix_spawn()
