Hmm... indeed it seems I was completely confused.

`process-send-string` is even a context-switch point, so it can
definitely do a non-local exit for all kinds of reasons (quit and
while-no-input being just some of the possibilities).

IOW, better disregard what I said in this thread, because I was talking
about things I don't know.
