Yes, fair enough. There are a lot of indeterminacies in the framework - for 
example, it might perform an animation for whose finish you get no 
notification, or you might need to wait until after the next "redraw moment" 
(as I call it) - and one gets into the habit of using delayed performance as a 
way of skirting these. But I certainly see why this is a different sort of 
case. m.
