As far as I know, ulimit ("user limit") won't help. It can limit the amount
of RAM available to a process, but that just makes the process start using
virtual memory more quickly. It can also limit the amount of virtual memory
used by the shell, but not of other processes. In other words, Linux will
try really, really, really hard to give you the 84 gigabytes you've asked
for on a 2 GB system, even if it means DOSing your system for a month.
Of course, I would be very happy to learn I'm wrong.
