  SVN rev 191209 on 2009-04-17 16:42:03Z by alc
  
  MFC r175055
    Defer setting either PG_CACHED or PG_FREE until after the free page
    queues lock is acquired.  Otherwise, the state of a reservation's
    pages' flags and its population count can be inconsistent.  That could
    result in a page being freed twice.
  
  (This change should have been included in the MFC of the superpages
  support.)
  
  Thanks to:      pho for an illuminating crash
