I object to the "obviously" above.

No, it's a bug.

I think the first step is to figure out what triggers this bug.
E.g. maybe run your Emacs under a debugger, place a breakpoint on

    Fthrow (Vthrow_on_input, Qt);

in process_quit_flag (in src/eval.c), then reproduce the problem.
Hopefully you'll be able to get a backtrace that gives a good hint at
why the while-no-input is interrupted.
