Thanks Bob,

I just tried that and indeed, after doing that and a GC, it removed almost
all garbage I have around and indeed, it called all the #unregistered of my
sessions.
So.... OK, with such code I can at least force the GC of those (which is
similar to the one I was doing: *WAApplication allInstances do: [ :each |
each clear ].)*  , but... I still wonder, why my sessions are not "reap"
automatically? Why they do not get the #unregistered automatically? From
what I understand, they should, right?
