Even though the POSIX behaviour is undefined for passed invalid thread
variables, cygwin1.dll locking up is not a pretty way to handle failure.


However, I'll consider removing the checks for non-debug builds of
cygwin, but _only_ once the in-cygwin code is considered stable and
complete. Until then I'm leery of having a no-check environment.

Still I've found what seems to be a good alternative function that is
_much_ faster, and still provides the reliability I was looking for.
