I've now been running 3.8.0-9.18 for the past day. Current memory usage,
according to free:

$ free
             total used free shared buffers cached
Mem: 3842480 3693604 148876 0 6464 1049600
-/+ buffers/cache: 2637540 1204940
Swap: 6291452 417872 5873580
$

So far the problem has not recurred. However, I would note that in the same
time frame I also installed a flashblocker add-on for my browser, so my
usage pattern may have changed.

I'll give things another day, then if the problem doesn't recur, boot back
into -10 to see if I can reproduce the bug again.
