From: Seija Kijin <doremylover123@xxxxxxxxx>
Use pthread_exit instead of async_exit.
This means we do not have
to deal with Windows's implementation
requiring an unsigned exit coded
despite the POSIX exit code requiring
a signed exit code.
Use _beginthreadex instead of CreateThread
since we use the Windows CRT.
Finally, check for NULL handles, not "INVALID_HANDLE,"
as _beginthreadex guarantees a valid handle in most cases
