So I bring up a terminal window and run "top". What do I see, but two (why two?) dosemu processed that are both running at 100 percent -- and have been since about 5 hours ago. Load average is 2.5. I kill both processes, the fan immediately goes quiet. Load averages drop (after a while) to the usual 0.28.
So this is odd and surely a bug -- but not my problem. Something perhaps to keep an eye on and report if I can nail down more precisely what of the dozens of things I did triggered it.
After my reinstall in 2024 I have not seen a repeat of this. I have seen other odd things, but nothing of this sort.
