 * Pick up task loop changes similar to recent ones to snarkbsd.c in the
 * ATTACHE_THREADS case (neatening it up before burial).
 *
 * Revision 1.32  1999/04/15 15:45:31  wes
 * Catch null function pointers with a BUG_ASSERT instead of blithely
 * leaping into the void.

 *
 * Revision 1.28  1998/12/16 09:09:07  sra
 * Add magic multicast support for Courier.  Change opcode for packet receive

 * same task as is usually calling attache. Fixes re-entrancy bug which crept
 * in when MUXD task went away and i consolidated timers.
 *
 * Revision 1.24  1998/09/22 21:57:53  meister
 * glue_pktalloc, glue_pktfree, glue_intlock really belong in attache/psos,
 * not snark/lib for this port.
 *
 * Revision 1.23  1998/09/22 19:39:26  wes
 * Since, at startup, there's a task already queued for us, check the task
 * queue at the top of the loop instead of the bottom..
