Not with unsecure migrations. But yes with secure ones this would be the
case, they would not crash but simply not work as the tcp tunnel is not

We could actually support the old one for some time, even if it is broken
(not our fault) as we see if we should open a tunnel or not, i.e. if the
raddr is
tcp and localhost then open a tcp tunnel like we did, if its tcp and not
localhost its
an unsecure and if its unix the do like in this patch.
