you can get similar effects by remapping things.
i meant that it isn't likely to happen by accident, so am i bovvered?
fault386 needs to be fixed mainly by or for people running a shared cpu
server with hostile users (ie, students).
for the rest of us it might be more useful to have the panic
to prevent real kernel bugs (ie, just bad pointers in device driver implementations)
from postnoting a process instead of stopping the system.
having said that, it could be argued that even in that case
a postnote to the invoking process would allow the rest of the system
to run and `might not' mean that the broken driver has wrecked other
data structures outside it in kernel memory.
