I *think* you'll find that if your module issues a prompt as well as
displays a message, the user will get the message.  You could just
have the message, then a prompt "Press return to continue", although
that can be damn annoying.  And I think there is an ordering problem
in openssh as well.

Anyway, try it out and see what you get.
