To expand on this; the proxy can't just arbitrarily t_relay() again after it has received a final negative reply. That's not what proxies do. The only way it can happen is if a proxy uses its forking capability, as described by the standard, to create a new branch to another destination. Only then would it be justified in keeping the final negative reply on the first branch opaque from the customer and pursuing other options.
