For example I object to the "obviously" above. > Is this expected, No, it's a bug. > and is there a way to avoid this behavior? 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. Stefan
