Re: Opening a pty without a process

[Richard Stallman <rms@gnu.org>]

       (defun open-pty-buffer (buffer)
	 (let* ((process-connection-type 'pty)
		(proc (start-process "foo" buffer "sh" "-c"
				     "while sleep 3600; do :; done")))
	   (process-tty-name proc)))

    I guess it would be convenient indeed to be able to use nil for the
    program rather than a contraption like the one above.  OTOH we could
    just use `hexl' by adding a flag to it (it's already abused in a similar
    way by `ielm').

I think it would be much cleaner to do this at C level
and dispense with the need to run any program in this pty.
