[ ditto ]

[ the workstation I am using has 126 processes, and six interactive
  users, many network services processes (and a preemptive scheduler
  :-), but I still get good response time ]

I am not suprised, with a Sun 3/60.  Ours are dogs, too, if more than
one person is logged in doing anything terribly productive.  Not too
bad, if used for a single-user machine, however.

I am using a Sun SPARCstation 1.  It's verra nice indeed.

A SPARC chip against a 68020 might seem a little unfair (or maybe not),
but the Sun 3/80 has a 68030 (like my Mac), and its response time is
very good; just one step below that of the SPARC.

  start going to a more appropriate newsgroup ]

"Zombies," I think, is the term you are looking for.
