New description:

 If a Tor instance is only doing onion service activity, and circuits time
 out, then the Tor client thinks that circuits aren't opened and gives them
 a full minute to complete. It also complains about this in the logs at
 notice level, like this:

 {{{
 Aug 06 02:55:30.000 [notice] No circuits are opened. Relaxed timeout for
 circuit 21570 (a Hidden service: Pre-built vanguard circuit 4-hop circuit
 in state doing handshakes with channel state open) to 60000ms. However, it
 appears the circuit has timed out anyway.
 }}}



 The fix is simple. circuit_any_opened_circuits() in circuitlist.c is only
 counting circuits as opened if they use the DEFAULT_ROUTE_LEN. We just
 need to count >= DEFAULT_ROUTE_LEN to count them.
