yeah, that's good enough. We want to have a minimum delay of 1 second,
because otherwise we'd be getting false positives under high load (and
under some bad drivers). Having a larger delay is not an issue, as long
as it's below the average hit-reset latency of users ;)
i'd expect the HPET-based __delay(1) to be the heaviest.
