I turned on kmemleak and was able to reproduce this on a second reboot,
but it went most of a workday before I noticed it had leaked a bunch.
Unfortunately, kmemleak didn't help at all. It found a few small things
that _may_ be leaks, but nothing to account for this _massive_ loss.
I'm stumped so far.
My next step is to add some logging to at least see if this is a gradual
thing or it happens all at once, and maybe figure out what the heck I'm
doing to trigger it.
