   Before you read my article, let me just say that I _do_ like the Macintosh.
   I own one, and I like it.

Good.  Otherwise, we would have to shoot you.  :-)

   [lots of stuff cut]

   I think that *both* mouse responsiveness and volume mounting should be
   provided at the same time.  It can be done.  Why do you not desire this?

   What?  Are you kidding?  The answer is "none."  The scheduler is part of
   the operating system, which is not represented as a process.

   There are, at this very moment, 126 processes on this workstation I am
   posting from.  Most of these processes (73) are concerned with network
   services provided by this machine.  Nfs, yellow pages, etc.

   The rest of the processes (53) are user processes.  There are currently
   six users logged on this machine.

   The responsiveness of my mouse pointer (or anything else for that matter)
   is instantaneous.  Just like my Mac.

What the **!@#? kind of machine are your running? I'm on a Sun 3/60,
with 3 users, running X; if I click the mouse once--not holding it
down or anything--the menu appears & disappears: this takes nearly 3
seconds (yes, I timed it).  Almost nothing is going on in the
background.  There are a total of 53 processes, 8 of which are dead
or something.
