Replaced a bunch of delay loops with a new delayUntil() function. Now all of

them will at least sleep if the remaining delay is at least 10 ms. (Personally,
I don't like the idea of busy-waiting even 9 ms, but now that it's in its own
function, it becomes much easier if we want to change that behaviour. There are
still plenty of custom delay loops left, though.)
