* 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`.
