This is indeed how I have in mind to implement restart. The problem is that once you build redraw/invalidate into the GUI you tend to start using it for other purposes, and it becomes a potential covert channel.

There is another issue, which is more "purist" in nature: the number of programs that get notified of a restart should be kept as small as possible.
