Heh, I think I found it! Whenever I start and exit a special Motif
application (non free) the memory increases by approximately 10MB. I did
it 100 times in a loop and got:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
 3789 root      15   0 11.9g 2.0g  10m S    0 28.6  61:06.52 Xorg  

The 2 GB values doubled it's size from initial 0.8GB!

But it is still an Xorg bug as the memory should be freed once the
applications ends, right?

The program itself initializes menus, allocates a few strings (probably
without freeing with XmStringFree), a larger pixmap and initializes OpenGL
(Mesa-6.5.1-23) without using it much in my case.

Shouldn't xrestop show this? Are there other tools?

Such as valgrind :-))
OK, now it is at least reproducable for me. There should exist also
a few faster memory checkers.

That's no problem for me.
