Now I'm trying to find the way to get real memory usage. I have written
a memory protector that kills a process which use more than max memory
and it doesn't work well with this forks because it counts output of ps
command:

> ps -e -o "vsz,pid,args"

 2848  6228 ruby f
 2848  6227 ruby f
 2848  6226 ruby f
 2848  6225 ruby f
 2848  6224 ruby f
 2848  6223 ruby f
 2848  6222 ruby f
 2848  6221 ruby f
 ...

It looks like every ruby interpreter needs 2MB, but if I run free, memory
usage is almost the same.

Have you any idea how to get the real memory usage of each process?

Thank you,
