"info": "This example shows how to use a delay node set to rate limit mode as a simple queue to feed a\nprocess that may take some time to complete. Once that process completes the feedback is then\nset to flush out the next message - thus running the \"loop\" as fast as possible with no overlaps.\n\n**Note**: only the `msg.flush` property msut be set - otherwise the other properties that are fed \nback will be added as another new message to the queue.",
