splxxx() keeps interrupts from occuring in sensitive code areas.
is it possible to have parts of the device driver code running while
an interrupt is being serviced? ie: an interrupt comes, and control
passes to the interrupt routine, can, while the interrupt routine is
running, things like tp->t_oproc be called?
or is everything else with that driver suspended while the interrupt
routine is running?
