ok. for me it is enough to unregister tcp (and udp) contact when tm
tries to reach it.  the only problem with that currently is that branch
failure route is not executed immediately, but after tm timer fires
although tm learns immediately that tcp contact is not reachable.

that sounds like a clean, good solution.
