        Hum, is that really needed? You can run UNIX for years without
a reboot. I assume our LispOS will have that for granted, and event
not require reboot, but just a (gc).

        That's a great feature. Can it be said that it reaches the
level of changing code on-the-fly, or even build a program while
running/debuging it. It could speed-up enormously development speed.
