This is highly unlikely: the "ZODB" (Zope object database)
uses pickle (actually, it is "cPickle", the "C" implementation
of the "pickle" module) for serialization. The "ZODB" is
used in long running Zope processes. Should pickling cause
significant memory leackage, this would have been observed
(and reported).
