  o Minor bugfixes (logging, relay shutdown, annoyance):

    - When a circuit is marked for close, do not attempt to package any cells

      for channels on that circuit. Previously, we would detect this

      condition lower in the call stack, when we noticed that the circuit had

      no attached channel, and log an annoying message. Fixes bug 8185;

      bugfix on 0.2.5.4-alpha.
