  Modified files:
    sys/sys              queue.h 
  Log:
  Add sanity checking for QUEUE(3) TAILQs under INVARIANTS (similar to
  the LIST checks).  Races may lead to list corruption, which can be
  difficult to unravel in a post-mortem analysis.  These checks verify
  that the prev and next pointers are consistent when inserting or
  removing elements, thus catching any corruption earlier.
