  Log:
  SVN rev 189502 on 2009-03-08 00:11:26Z by luigi
  
  MFC rev.188571
  
  Clarify and reimplement the bioq API so that bioq_disksort() has
  the correct behaviour (sorting by distance from the current head position
  in the scan direction) and bioq_insert_head() and bioq_insert_tail()
  have a well defined (and useful) behaviour, especially when intermixed
  with calls to bioq_disksort().
  
  See the original commit log for more details.
  
  NO API/ABI changes (except from fixing bugs and defining
  unspecified behaviour that no code should rely on).
