Copy of Model events

I was considering what needs to be done in #copy for some of my domain
objects that I had made subclasses of Model. I ran across the following
comment in Object>>postCopy.

"Apply any final flourish to the copy that may be required.
This should be overridden by subclasses which provide their own
storage (i.e. in instance variable(s)) for events/dependents in
order to release those (otherwise the copy will inherit them)."

So the question is... Is there some reason why Model isn't heeding this
advice for its "events" instance variable?

Good point. An oversight I would say, and one that has gone unnoticed for a
number of years. Thanks Bill (#1095).
