  SVN rev 207519 on 2010-05-02 16:44:06Z by alc
  
  This change addresses the race condition that was introduced by the previous
  revision, r207450, to this file.  Specifically, between dropping the page
  queues lock in vm_contig_launder() and reacquiring it in
  vm_contig_launder_page(), the page may be removed from the active or
  inactive queue.  It could be wired, freed, cached, etc.  None of which
  vm_contig_launder_page() is prepared for.
