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

16 * @typeParam Data - Type of data this worker receives from pool's execution. This can only be serializable data.
17 * @typeParam Response - Type of response the worker sends back to the main thread. This can only be serializable data.
