  Modified files:
    sys/vm               vm_map.c 
  Log:
  Two changes to vm_map_delete:
  
  1. Don't bother checking object->ref_count == 1 in order to set
  OBJ_ONEMAPPING.  It's a waste of time.  If object->ref_count == 1,
  vm_map_entry_delete will "run-down" the object and its pages.
  
  2. If object->ref_count == 1, ignore OBJ_ONEMAPPING.  Wait for
  vm_map_entry_delete to "run-down" the object and its pages.
  Otherwise, we're calling two different procedures to delete
  the object's pages.
  
  Note: "vmstat -s" will once again show a non-zero value
  for "pages freed by exiting processes".
