Hi Nicolas,

I saw your notes to http://bugs.squeak.org/view.php?id=7352 . Thanks for 
your careful and detailed review! I addressed all the issues you raise 
with new change sets, except those about WeakMessageSend subclasses. It 
seems that NonReentrantWeakMessageSend and ExclusiveWeakMessageSend are 
part of the Polymorph package. I believe they should modify them as needed.

Cheers,
Juan Vuletich
