I figured out that it's difficult to find out from /proc
which processes that share VM (created with clone(CLONE_VM)).
made a patch that adds in /proc/<pid>/status a VmClones field that tells
how many proc that uses the same VM (mm_struct). if there are clones I
add another field VmFirstClone with the pid of clone with the lowest
pid.
Needed for things like gtop that adds mem usage of groups of proc, or
else they add up the usage of SIZE and RSS of threads.
The patch need to be applied to linux/fs/proc/array.c
NB: developed on 2.4.3
