  29 /* HISTORY
  30  * 18-May-90  Avadis Tevanian (avie) at NeXT
  31  *      Changed to use sensible priorities (higher numbers -> higher pri).
  32  *
  33  *  1-Feb-88  David Golub (dbg) at Carnegie-Mellon University
  34  *      Goofed... netisr thread must run at splnet, because the routines
  35  *      it calls expect to be called from the softnet interrupt (at
  36  *      splnet).
