and it turned out that failure route is not called if t_relay() fails. the mystery is, why some times after calling drop() in branch route t_relay() fails and failure route is not called and some other times t_relay() succeeds and failure route is called?
here is a few test calls that show the unpredictability. six calls, two enter failure route after drop and four don't because of t_relay failure. the first one after proxy restart seems always enter failure route.
