	Make sure processes associated with the terminal are actually
dead before re-using the pty.  This is a temporary fix; the real fix
will make sure that the processes get a HUP when telnetd dies and will
be part of the libpty changes.

+	(cleanopen): Revoke on AIX as well.  This may cause problems on early 3.2 versions, but not revoking causes disconnected sessions to be partially connected to new telnets.  The complete fix will be to make sure telnetd cleans up when it dies.
