    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, an event is emitted. If you want to listen to this event, use the pool's emitter.
