I'm sure you can find many things wrong with this test case but I'm not
sending it for discussion on the merits, or certainly the lack of, an

Nope, PEBKAC.

Timer signals are delivered via ksoftirqd, so your cpu hog prevents
ksoftirqd frum running.

Does ksoftirqd deliver timer signals in vanilla?

Thanks
