Bug 106106 is about horrible X server graphics memory (GEM objects) leakage. 
To fix that bug, X just needs to free related object when it's done with it. 
Should be trivial.


This bug is about how to detect such leakage and be able control it in
processes.

I.e. kernel i915 module not providing visibility for graphics memory usage
(like happens for all other memory), and lacking means to control/limit
processes' usage of this memory in standard ways (out of memory killer, cgroups
etc).  

Fixing this will likely need a lot of talks with upstream, on how that should
be solved (API to rest of GEM, /proc/ API...).
