I have tried the attached patch and threaded Cygwin Python builds with
semaphore support instead of conditional variables.  Is the consensus
that this patch should be submitted to the newlib list?

Thanks,
Jason

How do you think this all got started? :-)

I have a patch from Jason, which I planned to post to
the patches list, although I haven't done one yet, so
I'll probably mess something up. :-)

It's a one-liner. I attached the patch here in case
you're interested. Is this the right format? It's
pretty straightforward, although I haven't really
had a chance to test it yet. I am insanely busy
right now.

BTW, I've done some investigation into the threading
issue, and it definitely seems to be related to that
race condition in Condition Variables, but I think
you knew that already.
