I believe it is up to date in 2.5.
Committed_AS certainly errs on the pessimistic side, that's
what it's about.  How much swap do you have i.e. is 23GB
committed impossible, or just surprising to you?  Does the
number go back to what it started off from when you kill
off the tests?  How are "those pages" allocated e.g. what
mmap args?

In my case it's not really possible to rerun a test in the same
boot. It's not really survived very often, and when it has, it
generally fails to start a second time. Various other things feel the
OOM sting then, e.g. kernel compiles, small task count dbench, etc.

Some of this might be slab, but I think there might be a leak.
The best answers I've come up with thus far are "Hrm, the OOM killer
gets set off at the wrong times, and maybe delalloc would kill bh's?"

Cheers,
Bill
