This seems only to happen after several hours of suspended ram sleep.  I
just waited this time to see if it ends, and after ~10 seconds, CPU
usage went to nearly zero and everything was good.  I'm not sure if
Emacs is to blame for anything, though I didn't see this before.  When
it happens the next time, I'll have a look if other programs are
responding.
