Then I really recommend you upgrade to 3.4. From What's New:
CPython implementation improvements:
 Safe object finalization (PEP 442).
 Leveraging PEP 442, in most cases module globals are no longer set 
to None during finalization (issue 18214).
You might find the issue discussion interesting.

Compile Python yourself. If you have trouble, post "Need help compiling 
3.4 on Gentoo" and I am sure you will get responses.
