Unfortunately, I don't think this is possible unless we add some
platform-specific code to thread.c, and you'll need to ask Uncle Timmy
for that. To the extent that I'm an expert on threading, I'm only an
expert on Python threads.
Unless someone is aware of some brilliantly simple solution, I think we
need to live with the ugliness for now, but I'd prefer to discourage
further efforts in the ugly direction.
