35 * Thread provides base class for implementing threads. To leverage that
36 * functionality, inherit Thread in your class and implement virtual run()
37 * method.
38 *
39 * \note Thread class is not thread-safe, i.e. thread control functions
40 *		 such as start() or join() can not be called from multiple threads
41 *		 concurrently.
