Hi Bill,

The 3.4 image includes a number of changesets that attempt to make the 
event system use weak references for registration.

I don't know what Dolphin has to do with this problem in Squeak, 

It's our intention to make this event system as clean and leak-free as 
possible. Could you poke around some more to see what's not getting 
GC'd? It could be that the actors are responsible for hanging onto 
the events, and something else is holding on to the actors.
