ok, i tried hard, but after my initial example fell apart (idle sizer
without size-request as discussed on irc), i can't come up with a scenrio
to break the invariants with your patch at the moment. and since your
patch does indeed fix my resizing bug, i gave you the benfit of a
doubt and applied your patch.

you agree on merging it down to 2.4?
