 > What is left to do here?

 In order to give hidden services with high circuit-build timeouts a chance
 of working, we need to modify the client code so that when a client's
 intro circ times out in state `C_INTRODUCE_ACK_WAIT`, the client leaves
 its corresponding rendezvous circuit open while it tries again with a
 different intro/rend circuit pair.  This will require creating another
 state for rendezvous circuits (stored in the ‘purpose’ field).
