Xorg leaking memory?

[Dennis Jacobfeuerborn <d jacobfeuerborn conversis de>]

Hi,
Since last week Xorg seems to leak memory for me. The usual suspect for 
this is Firefox but now Xorg seems to use up big amounts of memory all by 
itself:

This is what I get after running Xorg for about three days and with most 
application I usually run closed:
Top:
  virtual: 241m
  resident: 184m
xrestop:
  Pixmaps:   12387K total
  Other:      67K total
  All:   12455K total

This is what I get after a fresh X startup:
Top:
  virtual: 73616
  resident: 15m
xrestop:
  Pixmaps:   11804K total
  Other:      42K total
  All:   11846K total

That is with xorg-x11-server-Xorg-1.1.1-21.fc6.
Anybody else seeing this?

Regards,
  Dennis
