Yes, nice/renice and their I/O friend ionice (in my Debian
installation, it's part of the "util-linux" package) work quite
nicely. It's the memory-limiting that I wish would work.

Yes, I suppose you could have a watch-dog that will monitor memory
usage and then kill the process. I'd rather the process get an
out-of-memory error if it tried surpassing a set threshold (what
ulimit is *supposed* to do).
