Probably, but not immediately <wink>.  I've been seeing this for a long time
with Zope3-under-Python-2.3.  I'm as well qualified to figure out why as
anyone, and intend to, but since it doesn't stop the tests from running it's
at a low priority for me.  Best guess:  Python 2.3 does more-exhaustive
garbage collection at the end of a run that Python 2.2 did, and we're
cleaning up stale objects now that used to leak.  The msgs come out at the
right place to be produced by final Python cleanup, and that the msgs are
devoid of any information suggests that most of the interpreter has already
been torn down.  So all the signs point to a (surprising but harmless)
glitch when Python is shutting down.
