Yes, nearly complete implementation (only one key feature - cancellation
points - missing)... Oh signals per thread needs a little work.

Apparently the code is pretty fast :}. (Another project, an IBM
mainframe emulator bench tested cygwin threads vs Native threads vs
libpthread-win32 (another pthreads-on-win32 library, but unable to be as
complete as cygwin (can't assume a unix environment)), and native
threads where (of course) fastest, but we came out even with
libpthread-win32, and that was before some major speed enhancements.
