* It is used to interrupt a running thread when a timeout occurs.
 * The class provides methods to interrupt the thread and stop the timeout target.
 *
 * <p>
 * The class uses a logger to log debug messages.
 * It also uses an AtomicBoolean to track whether the thread is running.
 * </p>
 *
 * <p>
 * The expired method is called when a timeout occurs.
 * It interrupts the running thread up to a maximum number of times.
