Hook for doing any setup that should be done *after* the actor is
        started, but *before* it starts processing messages.

        For :class:`ThreadingActor`, this method is executed in the actor's own
        thread, while :meth:`__init__` is executed in the thread that created
        the actor.

        If an exception is raised by this method the stack trace will be
        logged, and the actor will stop.
