0071d67efd when only one router is labelled as a guard, and we've

1f0e20806b END_CIRC_REASON_OR_IDENTITY apparently means that we were told to
connect to a different OR than lives on the addr:port we connected
to. we don't actually remember whether that was the case, currently.

581795f41d auth dir servers were only modifying a server's is_running field
when they created a network status. so if nobody asked for a
network status, they would never discover that any servers are
is_running, so they could never build a circuit.

   for a new conn instead.

when Alice sent an extend request for a Tor that they're not connected

their sorry little lives in that state, even when the connection
was established and they were shuttling relay cells back and forth.
