[issue7060] test_multiprocessing dictionary changed size errors and hang

[Kristján Valur Jónsson]

Kristján Valur Jónsson <kristjan at ccpgames.com> added the comment:

The unittest only keeps an exception _object_ around, not the associated 
traceback.  There should be no frames and thus reference cycles associated 
with this.
I agree that the problem should be tackled, rather than swept under the 
carpet like a revert does.
