Based on that, backpatching the new win32_sema.c implementation is
probably more defensible than applying the proposed smaller patch
anyway; it's survived more testing.

My inclination is to do nothing to the back branches, but if we get more
field reports of trouble with them, maybe that's what to do.  (I'd be
happier if 8.2 gets through beta first, as I'm still a bit worried about
the do-all-Windows-versions-act-the-same bit.)
