If your i386 system has panic()ed in pmap_remove_all() recently, I would
encourage you to update your pmap.c.

  Log:
  Acquire the page queues lock in pmap_insert_entry().  (I used to believe
  that the page's busy flag could be relied upon to synchronize access to the
  pv list.  I don't any longer.  See, for example, the call to
  pmap_insert_entry() from pmap_copy().)
