   Now, what happens when an unprotected program tries to step on a protected.
   program?  I'd call that a task held.  It's not very nice but at least it
   stops the errant program from doing real damage.

No, it stops the errant program from doing any _more_ real damage. You
don't know what it's managed to trash before it tried to touch
something it wasn't supposed to. At this point, a reboot is just as
advisable as it is without the protection.

Not that a dual-universe system, with some programs running protected
and others running unprotected, is worthless. It doesn't stop the
programs in the unprotected half of the world from taking out your
system, but it'll stop programs running in protected mode from doing
so. That provides a great incentive to purchase programs written that
way, which will provide an incentive to develop programs that work in
a protected environment.
