If you want a busy loop, just comment out the sleep line. I don't see how that makes any sense, though.

Of course, it can, if you use a HiRes timer.

You have to use a timer either way. Or is hires somehow meaningful in that sentence? I don't see why, so could you give a example reason?

there *are* cases where it makes more sense

What would be such a case? I can't think of an example where doing a busy loop is acceptable if the system has a notification API. (In this case, sleep is that API since we're only interested in waiting for an amount of time.)
