Well, I was mostly interested in the relative call overhead. It's perhaps worth pointing out though that even without a callback, just calling SetWaitableTimer() with a 1 ms period would probably get the resolution close enough for our purposes. Whether that's a good idea is perhaps a separate discussion, but it would do for testing purposes at least.
