Thanks Eric

I checked the power management preferences and couldn't see anything
about CPU throttling, though I did verify it would never go to sleep
after inactivity. Then, I found some info on
calingcpu-throttling-in-ubuntu-jaunty9-04/ to disable the CPU throttling
(I know I am using 9.10, not 9.04, but I imagine it should be the same).

After rebooting (only once), I haven't yet seen the problem again.
Unfortunately, given the seemingly random nature of the problem, I guess
it is a wait-and-see matter as to whether it ever does resurface.

CPU throttling.  Check power management configuration.
