Not sure if everyone is talking about the same thing. This is still a problem (at least for me): http://svn.python.org/projects/python/trunk/Lib/test/crashers/weakrefindel.py It creates a weakref to self in del.

Yes, but that has nothing to do with the cycle collector. I even have a way to fix it, but I don't know if it breaks anything else...
