  Log:
  Improve the delay algorithm used in bgfsck.  From the author:
  
   shuffles the timing and sleep calls in bgfsck from:
  
   sleep timer_on io timer_off io io io io io io io
     to
   sleep io io io io io io io timer_on io timer_off
  
   The original method basically guaranteed that the timed I/O included a
   disk seek every time, which made bgfsck sleep for much longer than
   necessary.
