So we are saying that it is ok for process running with regular priority,
to be able to starve another process at the same priority from getting
any runtime for 21 seconds in a uniprocessor kernel, and this does not
indicate any problem with the scheduler implementation? This would mean
that for a HZ=100 kernel in 2100 rescheduling opportunities, the watchdog
thread was never selected to run?
