    kernel - Offset the stathz systimer by 50% of the hz timer
    
    * Offset the initial starting point of the stathz systimer by
      50% of the hz timer, so they do not interfere with each other
      if they happen to be set to the same frequency.
    
    * Change the default stathz frequency to hz + 1 (101hz) so it
      slides across the tick interval window.
