        - fix t/01pod.t and t/02pod-coverage.t to only run under

        [IMPROVEMENTS]
        - Downgrade a disconnect message from ERROR to SOCKET debug level
          in order to reduce the amount of runtime log output. Disconnects
          are /very/ common in HTTP, and shoudn't be considered errors.
