I forgot to add that getting widget off the screen is not the same as
destroying it.  removing a widget from the screen is not a resource
management issue and there should of course be explicit request to do
so and they shuld be honored all the time, without regard to the
reference counting.  But I can't say more about this right, as I don't
know what the difference is between showing, mapping and realizing a
widget.  One of these operation should be ablt to do the trick, I
think.
