Thanks for all the detective work! Your analysis is correct and your patch looks
good. I've always been suspicious of that code, and it looks like you've
confirmed my suspicions.
The only question in my mind is whether to install the patch into the emacs-27
branch or the master branch. Given Eli's problems with stability in emacs-27
(see Bug#41321), I'm inclined to think the former, as the bug could explain the
problems Eli is observing.
