std::thread dispatherThread = std::thread(
    [taskQueue]()
    {

        {
            bool processed = XTaskQueueDispatch(taskQueue,
                XTaskQueuePort::Completion, INFINITE);

            if (!processed)
            {
                // The task queue has been terminated, so return.
