One other problem with this is that until getchar returns, Emacs is
stuck, and nothing runs.  That's not a good thing, IMO, so I think the
implementation should go via wait_reading_process_output and stuff
(which will have a nice side effect of letting some other thread run
while Emacs waits for input).
