I'm approaching the limits of my understanding now, but:
I note that several of the shared libraries you list are specific to
the X server, and thus aren't shared by any other process.
I've never used memstat before, but the manual page states that it
reports "virtual memory". I was looking at the "RSS" (resident
segment size) column of ps. Virtual size can include things which
aren't main RAM. It would appear that memstat breaks out
memory-mapped files, but how does it treat things like pages swapped
to disk?
(I wouldn't expect RSS to include RAM mapped from the video card,
but I didn't know that for sure, hence my qualification earlier.)
