  Modified files:
    sys/vm               swap_pager.c 
  Log:
  Put an uncovered page between the swap devices, that way we can be sure
  to not get any cross-device I/O requests.  (The unallocated first page
  protecting BSD labels already gave us this, but that hack may go away
  at some point in time).
  
  Remove the check for cross-device I/O requests in swap_pager_strategy.
  
  Move the repeated statistics updating into flushchainbuf().
