Didn't you say before that, because of unlimited undo, you expected
unbounded growth?

Well, gc.get_objects() is a list of all container objects in existence.
Start by looking at it, to see whether unexpected stuff is in it.  If
something is in gc.objects() after doing gc.collect(), it's because it's
still reachable.
