If we do NOT account for this PIT issue, the result is a time drift that

Still, it is non-intuitive that a multi-GHz machine can't wake you up

What about telling it to wake up a jiffy earlier, then checking whether
the scheduling lag was enough to cause it to have waited the full
specified time. If not, put it to sleep for another jiffy.
