+ *        use schedule_gsm_timer to schedule a timer in
+ *        x frames from now...
+ *      - Use del_gsm_timer to remove the timer
+ *
+ *  Internally:
+ *      - We hook into select.c to give a frame number of the
+ *        nearest timer. On already passed timers we give
+ *        it a 0 to immediately fire after the select.
+ *      - update_gsm_timers will call the callbacks and remove
+ *        the timers.
