  Modified files:
    sys/sys              buf.h 
  Log:
  Add disk I/O scheduling for positively niced processes.
  When a positively niced process requests a disk I/O, make
  it wait for its nice value of ticks before scheduling its
  I/O request if there are any other processes with I/O
  requests in the disk queue. For all the gory details, see
  the ``Running fsck in the Background'' paper in the Usenix
  BSDCon 2002 Conference Proceedings, pages 55-64.
