You might want to do statistics that take into account the amount of
memory shared between processes. I don't know the right way to do this,
because there might be only partial sharing overlap between all the GNOME
programs, and some of that sharing figure might include libc etc.
Obviously in order to be accurate one needs to treat the shared memory
specially.

Also, in general RSS figures are very useless. All they tell you is how
much of the program is in memory (as opposed to being swapped out), which
doesn't necessarily give a good idea of total memory usage.

It is cool that someone has done this :)
