Summary: gc.collect sometimes hangs

Initial Comment:
When run under Python 2.1 on Mandrake Linux 7.2 (kernel 2.2.17) the attached script
terminates normally.  When run on the same machine under Python 2.2b1 it
runs forever, printing an infinite sequence of "No such attribute __del__" messages
to stdout.

If you comment out the call to gc.disable in Container.refresh, the script terminates normally
under both versions of the interpreter.

Assigning to Neil Schemenauer, our GC expert.

Note that in 2.1, I get a whole bunch of messages "No such
attribute __del__" to stdout too -- but it stops.

In 2.2, the *first* call to c=Container() and c.delegate()
does the same thing. But the *second* call to Container()
causes an infinite number
of messages to print (even if it's not deleting the first c
instance).
