 /**
  * A cluster pool with a dynamic number of workers, but a guaranteed minimum number of workers.
  *
  * This cluster pool creates new workers when the others are busy, up to the maximum number of workers.
- * When the maximum number of workers is reached, an event is emitted. If you want to listen to this event, use the pool's `emitter`.
