We would limit physical ram, not virtual ram. If you do a "man setrlimit", I'm talking about RLIMIT_RSS. The result would be slowing down and swapping, not crashing.
But will this really work? For example FreeBSD's manpage says:
``RLIMIT_RSS The maximum size (in bytes) to which a process's resident
set size may grow. This imposes a limit on the amount of
physical memory to be given to a process; if memory is
tight, the system will prefer to take memory from pro-
cesses that are exceeding their declared resident set
size.''What I have problem understanding is the last sentence of this paragraph in the light of your claim that it will results in swapping especially when we consider developers' machines with 512MB/1GB RAM, i.e. machines where memory is not "tight".
