Ah...don't know how I managed to miss that one.

That version is a lot slower than it could be.  MethodDictionaries
#become: themselves when sent #rehash...that method should probably be
changed such that the become is deferred to the end and all method
dictionaries get swapped in a single #elementsExchangeIdentityWith:.

I added a method called rehashEntireImage to SystemDictionary that is
much faster.  I see that #rehash is implemented all the way up in
ProtoObject...is this really necessary?  Symbol class is the only
non-Set that appears to implement #rehash.  It seems like someone was
expecting there to be a reason that all objects might need be sent the
rehash method.  Anyway, I like having #rehashAllSets implemented in the
Set class rather than my version on SystemDictionary.
