    necessary with content-headers and content-bodies into complete methods.

    Normally a method is represented as a tuple containing
    (channel, method_sig, args, content).

    In the case of a framing error, an :exc:`ConnectionError` is placed
    in the queue.

    In the case of unexpected frames, a tuple made up of
    ``(channel, ChannelError)`` is placed in the queue.
