i have noticed that i need to call again t_on_branch, t_on_reply and
t_on_failure in failure route before calling again t_relay, i.e.,
successful call of t_relay resets these settings and they need to be
re-armed.
how about if t_relay fails and transaction is not created? are the
t_on_X calls still in effect or do they need to be re-armed again?
i haven't found in tm/README any discussion about when the t_on_X calls
get reset.
