After a mostly-off-List discussion with Mr. Sanchez, I gave up and did a
"shutdown -r" on the system.
After a re-IPL, Gnome was back to gnormal, and everything else was back
up as well.
It's not like it's an AS/400, or even a state-of-the-art Linux box,
that's designed to run for years at a time without an IPL -- it's an old
Dell PowerEdge 400SC.
And I'd forgotten: it DOES have RAID: a hardware RAID controller with
two mirrored pairs on it.
No sign of damage to the mirrored pairs, but a full cold-start might be
necessary to be sure of that, if not an actual controller-level diagnostic.
