Looking at the Python/thread_*.h files, it looks like py3k still
supports 9 different threading models. If that's accurate, it means
py3k trunk is broken on platforms which use cthread, lwp, os2, pth,
sgi, solaris and wince threading models. The 2.x series adds atheos and
beos to that list.

I think the right way to fix this is to extend the thread_*.h files to
have a proper abstraction for conditions which can be used by the
newgil work. Then the maintainers for more obscure platforms can fix
those instead of it all turning into a big mess in ceval_gil.h.
