I was able to create a small self-contained test case from this description,
and opened a Collector issue containing it:

As it says, I don't know whether it "should work", but offhand don't see why
not.  As is, creating new state inside __getstate__ is confusing the heck
out of ZEO's MVCC cache "for some reason".
