    kernel - Offset the scheduler clock systimers
    
    * Offset the scheduler clock systimers slightly on each cpu so they
      do not all fire at the same time.  This is an attempt to reduce
      qemu contention due to its global I/O mutex.
    
      Note that the hz and stathz main system clocks already use this
      feature.
