// Paraphrased from: https://www.baeldung.com/kotlin/create-thread-pool
// "A cached thread pool such as one created via:
// `val executorPool: ExecutorService = Executors.newCachedThreadPool()`
// will utilize resources according to the requirements of submitted tasks. It will try to reuse
// existing threads for submitted tasks but will create as many threads as it needs if new tasks
// keep pouring in (with a memory usage of at least 1MB per created thread). These threads will
// live for up to 60 seconds of idle time before terminating by default. As such, it presents a
// very sharp tool that doesn't include any backpressure mechanism - and a sudden peak in load
// can bring the system down with an OutOfMemory error. We can achieve a similar effect but with
// better control by creating a ThreadPoolExecutor manually."
