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 and workers are busy, an event is emitted. If you want to listen to this event, use the pool's
+emitter.
