+ * - `'busy'`: Emitted when the number of workers created in the pool has reached the maximum size expected and are executing concurrently their tasks quota.
+ * - `'full'`: Emitted when the pool is dynamic and the number of workers created has reached the maximum size expected.
+ * - `'empty'`: Emitted when the pool is dynamic with a minimum number of workers set to zero and the number of workers has reached the minimum size expected.
+ * - `'destroy'`: Emitted when the pool is destroyed.
+ * - `'error'`: Emitted when an uncaught error occurs.
+ * - `'taskError'`: Emitted when an error occurs while executing a task.
+ * - `'backPressure'`: Emitted when all worker nodes have back pressure (i.e. their tasks queue is full: queue size \>= maximum queue size).
