My mistake; I didn't understand slabinfo very well at the time... and
(embarassingly enough) that was related to my piping the output to a file
(in order to do a diff later) rather than a regularly-occurring phenomenon.

As for my memory leak problem, I did finally track it down to the
kernel-preemption patch... my best guess is that it interacts poorly with
some of our platform-specific modifications... though what I can't figure
out is why even with preemption disabled (in menuconfig), I still have the
problem. I'm looking through the patch again to try to find additions that
aren't #ifdef'd out when it's disabled, but I have a feeling that since I've
found a way to fix the problem, I'll be moving on to other things soon.

Anyway, thanks to everyone who offered advice, and if any kernel preemption
experts want to set me straight, feel free!
