Yeah, it's just a bit odd that it's always in the IO path. Makes me
suspect there's actually a bunch of pagecache in the box as well, but
maybe it's just coincidence, and the rest of the box really is full
of anon mem. I thought we dumped the alt-sysrq-m type stuff on an OOM
kill, but it seems not. maybe that's just not in mainline.

Difficult to tell, it's a fairly new box to the grid, so it seems to
have been doing that intermittently forever.
