I had the following issues when I configured Python to use your pthreads
support:

1. To compile I had to apply the attached patch to sys/signal.h.  IIRC,
this is a known issue.

2. The Python regression tests run much slower with pthreads enabled
than without.  Also, the CPU seemed to be pegged at 100% more often
with pthreads than without.

3. The Python regression tests consistently crash during test_popen2
with the following error message:

    H:\src\Python-2.1b2a-threads\python.exe: *** couldn't release memory 0x1A02C000(5013504) for 'H:\src\Python-2.1b2a-threads\build\lib.cygwin_nt-4.0-1.3.0-i686-2.1\imageop.dll' alignment, Win32 error 487

I've attached the stackdump for your perusal.

Thanks,
