      A thread pool with a dynamic number of threads, but a guaranteed minimum number of threads.

      This thread pool creates new threads when the others are busy, up to the maximum number of threads. When the maximum number of threads is reached and workers are busy, an event is emitted. If you want to listen to this event, use the pool's emitter.
