    Try the classic ~. to exit.

    After you type exit it does look as if ssh hangs.
    That is when you type the two characters '~.'.

    I was also going to suggest the use of /usr/bin/screen.

    There are more than a couple situations where you
    still have an association with a controlling terminal
    and funny stuff with job control take place.
