LOL!  Been there many times before:  Python's gc really does work, but
it's as unforgivingly delicate as any dance you're likely to learn
while still mortal :-)  This one was actually typical, ending with an
unlikely comedy of errors involving microscopic details of how
multiple objects' cleanup routines could barely manage to fool each
other into tearing down an object more than once.  Until you get to
that point of clarity, it's also typical to fear that it can never be
fixed ;-)

You and Thomas did a wonderful of job of tracking this one down
quickly.  Good show!  Take Easter off -- but only if you have to :-)
