Jeremy and I were brainstorming this yesterday and couple of things
that we thought might be interesting are to:

 - turn on CONFIG_DEBUG_PAGEALLOC
 - turn on CONFIG_DEBUG_LIST
 - turn on CONFIG_DEBUG_KMEMLEAK
 - turn on CONFIG_JBD_DEBUG, CONFIG_JBD2_DEBUG
 - turn on CONFIG_SLUB_DEBUG_ON

And see if anything starts coming out.

Also looking in the changes for the drivers/dm/ between 2.6.32 and 2.6.38 and
see if we just hitting some memory leak bugs that hadn't been back-ported.

(Still busy with the upstream effort, can't work on this).
