It appeared that this was a critical issue. It took a bit of time to
track it down, and Lukas patiently assisted me in the process :). The
problem was a Glamour one and it was exhibited specifically in the
case of the MoosePanel like this:
Because MoosePanel registers for the announcements from MooseModel
root, even if you close it, this instance of MoosePanel will still be
referenced by the MooseModel root announcer. So, it does not get
garbage collected. And if you opened already a model with this
MoosePanel, this model will still be referenced by the Panel, and so
it won't get collected.
The current solution is that when the Glamour Morphic window is
closed, the announcements are unregistered from all enclosed
So, it means that in the case of MoosePanel, the garbage collector
will do its job only after you close the MoosePanel. It's not nice,
but it is the current solution.
will keep it open for a while. Please let me know if you find more

You could probably reproduce this problem in a new smaller image as
well. No need to spend the time doing it on a very large one.
