One reason I asked this, is because uEmacs has a variable to control
restartibility.  Does anyone actually turn this off?

So, then should all apps be written to use rexit()?  I don't really see
any reason to -not- make an app restartable, but then I have 4.25 megs
of memory, and want -everything- restartable :)

Hm, a couple of questions I just thought of re: restartability:

I've noticed that, if I have a restartable program running in the
background, and try to run the same application in the foreground, it will
not restart.  No surprise, that's to be expected.  But, even after one
execution, this copy of the app won't restart.  So, is it to be presumed
that there can only be one copy of a given restartable application in memory
at a time?  Is it possible, in a multiuser system, for someone (for example)
on console to use a restartable program, then exit, and for another person
not on console to use the copy in memory?

On the i/o-slow GS, restartability would be a great boon in a multiuser
system.  Running a cached application would allow the rest of the system
to operate at the same time, instead of lagging as the disk is accessed.
Allowing multiple copies of cached applications in memory would be nice
but I guess that isn't the way it works.
