does it make sense to have to have WeakMessageSend not been reentrant?
Because we could merge
WeakMessageSend and NonRentrantWeakMessageSend.Or we could move the two subclasses of WekMessageSend to the same package as WeakMessageSend or alternate solution. Rename Polymorph-EventEnhancements into Kernel-Enhancements. What do you think? Stef
