 Just a note that in my experience it has always been sufficient in this
 circumstance (as far as I can recall) to simply exit normally from
 cu/tip; I don't recall ever having to KILL it. Typing the following has
 i.e. carriage-return, tilde, then a period (or control-d) (assuming the
 default "~" escape character).
 I don't recall off-hand whether I've done this on 8.x, but certainly it
 has worked up to 7.4.
