11 | * When this worker is inactive for more than the given `maxInactiveTime`, |
12 | * it will send a termination request to its main thread. | |
13 | * | |
14 | * If you use a `DynamicThreadPool` the extra workers that were created will be terminated, | |
15 | * but the minimum number of workers will be guaranteed. | |
