+ * expire_timer_context() drops all current timers associated with

+ *
+ * run_timers() is called from the front end when it has reason to
+ * think some timers have reached their moment, or when it simply
+ * needs to know how long to wait next. We pass it the time we
+ * think it is. It returns TRUE and places the time when the next
+ * timer needs to go off in `next', or alternatively it returns
+ * FALSE if there are no timers at all pending.
+ *
+ * timer_change_notify() must be supplied by the front end; it
+ * notifies the front end that a new timer has been added to the
+ * list which is sooner than any existing ones. It provides the
+ * time when that timer needs to go off.
