Assume X went crazy (lacking any statistics, I make the unproven
statement that this happens more often than kthreads going berserk),
then having it niced with minus something is not too nice.
i've not experienced a 'runaway X' personally, at most it would crash or
lock up ;) The value is boot-time and sysctl configurable as well back
to 0.
Mmmm.. I've had to kill off the odd X that was locking in 100% CPU usage.
In the past, this has happened maybe 1-3 times a year or so on my notebook.
Now mind you, that usage could have been due to some client process,
but X is where the 100% showed up, so X is what I nuked.
