To clarify: One node will be hosting multiple clients' code, and if it
runs out of physical memory, performance for everyone else will be
severely impacted. So I'm hoping to restrict the script's ability to
consume all of memory, without (preferably) ulimit/rlimiting the
entire process (which does other things as well). But if it can't be,
it can't be.
