+/* The event queue maintains a single absolute time using two
+ variables.
+
+ TIME_OF_EVENT: this holds the time at which the next event is ment
+ to occure. If no next event it will hold the time of the last
+ event.
+
+ TIME_FROM_EVENT: The current distance from TIME_OF_EVENT. If an
+ event is pending, this will be positive. If no future event is
+ pending this will be negative. This variable is decremented once
+ for each iteration of a clock cycle.
+
+ Initially, the clock is started at time one (0) with TIME_OF_EVENT
+ == 0 and TIME_FROM_EVENT == 0.
+
+ Clearly there is a bug in that this code assumes that the absolute
+ time counter will never become greater than 2^62.
+
+ To avoid the need to use 64bit arithmetic, the event queue always
+ contains at least one event scheduled every 16 000 ticks. This
+ limits the time from event counter to values less than
+ 16 000. */
