In theory it is possible to do things like redirection of interrupts to the
appropriate intel processor level. WINNT has this sort of capability.
The issues here are:
You start limit the portability of the OS between different processors.
The overheads associated with the intervening code.
Do we really expect/want linux to be a realtime OS?
Surely all realtime code should be restricted to the the kernel and device
drivers.
