  SVN rev 183201 on 2008-09-20 11:26:13Z by marius
  
  Use the STICK timers only when absolutely necessary, i.e. if a machine
  consists of CPUs running at different speeds, for driving hardclock as
  these timers in turn are driven at frequencies as low as 5MHz, resulting
  in bad granularity compared to the TICK timers. However, don't employ
  the workaround for the BlackBird erratum #1 when using the TICK timer
  on machines with cheetah-class CPUs for performance reasons.
