Correct (the latter). :-) The "bandaid" in 239304 **wasn't** to fix a
bug introduced in 238214, it was an overall "bandaid".
I've gotten in the habit of always examining two commits (fix + previous
commit) to see what got introduced where.

Yes exactly. I just want to make sure Ryan understands that this is
simply a workaround for said spurious interrupt scenario, while the
actual root cause needs to be dealt as you describe.
