You can use SysRq-K to kill everything on the current console. Unfortuantely,
this does not work in X, and it's been screwing up my console lately.
But a SysRq real-time killer is a good idea. I might just code one for
the fun of it. A watchdog might be a better idea -- a high priority
real-time processes that watches to make sure SCHED_OTHER processes get
scheduled.
