July 1996 version is busted. January 1998 "release" isn't much better.

If you need optimized 'critical section' for Win95/i386 (it doesn't 
have CAS), try this swap/exchange based beast:

If you have CAS or LL/LR-SC,

and for recursiveness simply add a TLS/TSD flag:

P.S. For posix safety with respect to destruction, use "pimpl" and 
don't destroy event (reusing it for something that can live with 
"spurious" wakes on it [e.g. for another "impl" owner mutex] is ok).
