cPickle segfault with nested dicts in threaded env

[Thomas Jollans]

On Wednesday 08 September 2010, it occurred to Kenneth Dombrowski to exclaim:
> Environment is FreeBSD 8, Python 2.5.5

Which architecture?

Also, Python 2.5 is frightfully old. There's not really any problem with still 
using it, but nobody's maintaining it upstream, so don't bother reporting a 
bug with Python 2.5, as you'll just be told to test a newer version. Check if 
this still occurs in Python 2.7 and/or Python 3.1, and, if it does, then 
please do report the bug.

Chances are this was actually fixed a couple of years ago. See:

(and http://bugs.python.org/issue3338)
