από το README των Nvidia Drivers (τυχαίο που είναι nvidia, απλώς αντί να 
ψάχνω για το συγκεκριμένο resource στο Xfree site, ξέρω πως η απάντηση 
κρύβεται στο /usr/doc/ μου ;)

Q: Why does X use so much memory?

A: When measuring any application's memory usage, you must be
   careful to distinguish between physical system RAM used and virtual
   mappings of shared resources.  For example, most shared libraries 
exist
   only once in physical memory but are mapped into multiple processes.
   This memory should only be counted once when computing total memory
   usage.  In the same way, the video memory on a graphics card or
   register memory on any device can be mapped into multiple processes.
   These mappings do not consume normal system RAM.

   This has been a frequently discussed topic on XFree86 mailing
   lists; see, for example:

    http://marc.theaimsgroup.com/?l=xfree-xpert&m=96835767116567&w=2

   The `pmap` utility described in the above thread and available here:

    http://web.hexapodia.org/~adi/pmap.c

   is a useful tool in distinguishing between types of memory mappings.
   For example, while `top` may indicate that X is using several hundred
   MB of memory, the last line of output from pmap:

    mapped:   287020 KB writable/private: 9932 KB shared: 264656 KB

   reveals that X is really only using roughly 10MB of system RAM
   (the "writable/private" value).

   Note, also, that X must allocate resources on behalf of X clients 
(the
   window manager, your web browser, etc); X's memory usage will 
increase
   as more clients request resources such as pixmaps, and decrease as
   you close X applications.
