[Toolserver-l] per-user memory limits now enforced

[River Tarnell]

hello,

after a few incidents where processes using excessive amounts of RAM
have caused problems for other users, i have written a small program to
regulate user memory usage.

it works as follows: if the combined memory usage (RSS) of all your
processes exceeds 2000M, your processes will be killed in decreasing
order of memory usage until you are using less than 1000M.

you will receive email if any of your processes are killed because of
this.

these limits were chosen because they should affect no legitimate users.
let us know if you need more for some reason.
