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/weakref_in_del.py

It creates a weakref to self in del.

There are 7 crashers, plus 5 more due to infinite recursion. :-( That doesn't include the parts of test_trace that are commented out. At least test_trace needs to be fixed prior to 2.5.
