I'm not using hpet because it's an old hardware, this is with timer_tsc.
It must be reproducible in any machine out there, especially with
machines with usb it should be reproducible even without any userspace
testcase doing iopl/cli/sti. Time will go silenty in the future at every
usb irq (they often last 3/4msec).
