I think the difference in behaviour between Py3 and Py2 is coming from:

http://hg.python.org/cpython/file/a26df2d03989/Objects/dictobject.c#l1275

which first clears all values before removing any keys. For a WeakValueDictionary that means all the weakrefs are neutralized before the can be activated. I don't quite understand how Py3 manages to avoid problems for a WeakKeyDictionary, but apparently it does.
