Ugh. Not 100% sure it's related, but I've been getting a similar traceback when
running pip's test suite (python setup.py test) on OSX 10.6.8 with Python 2.7.2.

Ok, I think the reason this doesn't appear in 3.2/3.3 is the fix for issue1856.
In 2.x (and 3.1) daemon threads can continue executing after the interpreter's
internal structures have started being destroyed.
The least intrusive solution is to

In Antoine's patch, ISTM that the line

I can confirm this but with Python 2.7.1 on Ubuntu 11.04 64bit
My code was working with a queue that was being fed a two-string tuple.
When i changed it to contain my custom Objects, it still worked correctly, but

For what it's worth, I think I have a simpler reproducer of this issue. Using
freshly-compiled python-from-trunk (as well as multiprocessing-from-trunk), I
