Maybe we should attack the problem from that angle? Have a way when making a requestAnimationFrame call to specify when that animation should be considered "done" if the page wants, have jQuery update to do that, and then use that information to either do a single tick past the done time or drop the callback on the floor entirely once the done time passes? -Boris
