It's a shame that Python 3.x is dead to you, otherwise you'd be able
to enjoy the new GIL implementation in 3.2: http://www.dabeaz.com/python/NewGIL.pdf
Actually, it looks like you probably still can:
+ patch for 2.5.4: http://thread.gmane.org/gmane.comp.python.devel/109929
+ patch for 2.7? http://bugs.python.org/issue7753
(Can't comment on affinity, though, sorry)
