- But still, if something totally lock the computer,
- a heavy priority task goes into an infinite loop, you
- can't return to the os (not on a HP-unix atleast) and it will be lost
- even if you have tons of mem protection (or you can sit back
- and watch it run for some years)
-
- I've never crahed and lost any lightwave stuff exept when running my
- own shitty asm or demos. If something crashes I mostly get
- the suspend/reboot stuff, and suspend it. Then everything goes on,
- just with slightly less memory...
