 *
 * Thread provides base class for implementing threads. To leverage that
 * functionality, inherit Thread in your class and implement virtual run()
 * method.
 *
 * \note Thread class is not thread-safe, i.e. thread control functions
 *         such as start() or join() can not be called from multiple threads
 *         concurrently.
