 prepend a reject rule for this ip:port to our local version of the relay's

 come back to it with. But that seems a small risk compared to the risk of
 an exit relay with a complex enough policy that it causes clients to spend
 two circuits for fetching each component of web pages.

 It's not such a small risk for an IPv6-capable web-browsing client.

 How hard would it be to put that ‘tag’ on the circuit's data structure
 instead of the relay's?
