Depends on what the cpu_intensive_process does. If it tries to allocate
lots of memory, maybe. If it's _just_ CPU (as in `perl -e '1 while 1'`),
you get a chance that you can input some commands on a terminal to kill it.
SCHED_FIFO'ing or SCHED_RR'ing such a process is sudden death of course.
Sysrq+n changes all realtime tasks to normal priority.
