  Modified files:
    sys/vm               vm_page.c vm_page.h vm_pageq.c 
  Log:
  Add a page queue, PQ_HOLD, that temporarily owns pages with nonzero hold
  count that would otherwise be on one of the free queues.  This eliminates a
  panic when broken programs unmap memory that still has pending IO from raw
  devices.
