Isolation by MMU is a separate issue.  If you wish you can
think of a Lisp machine as analogous to Inferno, with Lisp as
its virtual machine language!  Also Lisp machine != emacs.
In any case even you admit (with your parenthetical
"Probably") that while at process level there is isolation
you can still run into trouble as there may be higher level
dependencies.

I understand that well.  My point was only that what Roman
wanted was already available 25+ years ago; not that it was
perfect -- too bad that branch got pruned too early.

In any case Plan 9 and LM are still like working under the
hood or playing with legos.  If you just want to drive your
lego car soon you discover they don't make great cars (even
great toy cars).
