Choosing overcommitment on a per-process basis sounds like a good idea (though
probably painful to setup since you'd have to specify process by process, but
you could probably have a default of overcommit==(! user==root)).
Turning off overcommitment doesn't save you from figuring out what to do when
you run out of memory (return NULL from malloc is very nice, but if this malloc
was executed by /sbin/init, it might not be such a good idea).
