Resident memory size limits

[Nord]

Does anybody know the way to limit resident memory size for the particular process?
I've played with ulimit options, it has several options concerning memory limits, but none of them does exact the same what i want.

ulimit -v limits the virtual memory size. But many programs reserve much more memory than actually needs, so it is not the best solution,
ulimit -m means nothing for my system (does anybody know what this option means?)

Any suggestions?

From what I gather, you are looking to "force" limits on a particular user/process, not have the user/process "volunteer" to use less resources.

All of the "mainframe" OS's have that feature, so I don't imagine it will be long before it finds it's way into Linux.

And yes, I would like to see it too! (memory limits, I/O limits, better CPU scheduler, etc).

Even toyed around with the idea of hacking on together myself.
