 * @brief       test application for xtimer_msg_receive_timeout()
 *
 *              This test will start sequentially start 10 xtimers to send a
 *              IPC msg, alternating with an interval of 900ms and 1100ms
 *              respectively. Everytime a timer was set, it will wait for a
 *              message for at most 1000ms. This should succeed and fail in an
 *              alternating manner.
