          :type queue_name: str or unicode
          :param queue_name: The name of the new queue.  Names are scoped to
                             an account and need to be unique within that
                             account.  Calling this method on an existing
                             queue name will not return an error from SQS
                             unless the value for visibility_timeout is
                             different than the value of the existing queue
                             of that name.  This is still an expensive operation,
                             though, and not the preferred way to check for
                             the existence of a queue.  See the
                             :func:`boto.sqs.connection.SQSConnection.lookup` method.

                                     be overridden on a per-message.
