Why do we keep cranking up this clock frequency? Do we really need
it running that fast? Is it time for someone with RTOS experience to
implement a real scheduled clock queue in Linux instead of just
wasting interrupts decrementing a counter waiting for the next
event to expire? :-) If the user "ticks" are still 100 Hz, don't we
something that is an integer multiple of that for at least an attempt
at getting it close to what a user would request?
