 Er, that one wouldn't work of course. I wonder how often and if at all this 
is one used though. The rest should be still doable.

 That's not hacks, you just make the dialog say it belongs together with A's 
windows. Also, B doesn't need to actually recursively enter the event loop, 
so it can handle even more of them at the same time.

 I've heard Windows and MacOS X already have their system dialogs :), so this 
apparently doesn't need to apply to them. Anyway, the interface looks good 
enough, in case somebody actually starts doing something about that for real.
