I think all the sem_* functions are broken similarly.  I have the threads.cc file modified 
and was going to try and submit patches, but I am having some issues getting
the regression tests working (even before I put my changes in...)  A soon as
I get these issues resolved and verify my fixes, I can try and submit 
a patch for everything (like all good cygwin users should!)  (Unless of course you
beat me to it - and at this rate - you will!)

Thanks for helping me out with this.

FWIW, I've patched sem_trywait and sem_wait. I haven't looked for further cases of misbehaviour though.
