[desperate plea on]
Some of us see the memory protection stuff as EXTREMELY useful.  I would
prefer an operating system that protects us from POORLY WRITTEN
PROGRAMS!  That way, many programs can be used with some assuredly that
if they are poorly written and misbehaved that they won't mess up any
other processes.  I love the core dumps on the Sun workstations here at
the University.  They let you know if a program is a misbehaving without
any damage to other processes.  I'm sure some day I will be programming
while having all sorts of other tasks running in the background.  I know
that I don't always get a program right the first time, so if my
operating system doesn't take care of my mistakes, the other things running
will not necessarily be kept secure.  So therefore the usefulness of
having a multitasking system will be minimized.
