When we use an object and not a model the dependents are stored in a
global dictionary or structure and our goal is to remove it :)

I had a look at dependents.
I see code in Object and Model which looks like quite close.
And also the comment in Model says: Provides a superclass for
classes that function as models. The only behavior provided is
fast dependents maintenance, which bypasses the generic
DependentsFields mechanism. 1/23/96 sw
Is there a place where I can read more about that and/or can
someone provide a quick explanation?
From memory and use of other smalltalks (VisualWorks): Model provides
an instance variable for storing dependents (which are then non-weak),
Object instances use a global, weak array.
At least, this is how I use them.
I allways have worries about discarding objects with dependencies
(Morphs, models) and creating memory leaks that way.

Right. I should have realized that.
I was looking for a replacement for:
Transcript closeAllViews
which has disappeared in Pharo 3.0. So this seems to work:
(Transcript dependents select: #isSystemWindow) do: #close
Thanks,
