For getting started with Smalltalk, Squeak and Morphic, I tried to write
yet another Counter example - separating the model from the view and
using the new event design which is very similiar to that of
VisualWorks, as far as I can see from the VW Application Development Guide.

It is also there that I read that you have to remove all registered
event handlers (using Object's event mechanism) yourself - quite painful
for someone used to garbage collection. And indeed I found out I
generated lots of entries in the EventManager's ActionMap (though I
confess I hardly understand how it works).

I thought about two ways to handle this problem:

1. I added a finalize-method to my model:
~   CounterModel>>finalize
~     super finalize.
~     self releaseActionMap

As of now I could not see any effects. Is the code wrong or is it just
because the garbage collector has not started its work yet?

2. Maybe it is a viable alternative that my model registers its interest
in the moment of destruction of its morph. But to subsribe for a further
event does not seem to be a very elegant solution in my eyes.

Can anybody help me out?
