xorg log

After some time my system is unusable because I have 3.5G of
active/unreclaimable shmem. So I put a printout to shmem_file_setup and
shm_destroy and I see only:
  shmem_file_setup: Xorg drm mm object
pretty often without shm files being destroyed afterwards.

This is exploitable by browsing maps in a browser very quickly. A minute ago I
had
  Cached:           695024 kB
browsed a map in firefox and now I see:
  Cached:           759500 kB

(This is output of "sync;echo 3 > /proc/sys/vm/drop_caches ;grep Cached
/proc/meminfo".)

Didn't you change something in the ddx lately? This started happening like a
week or two ago...

This happens both on ivb and g33.</pre>
