					   y_timers - Run timers efficiently. 
					  ====================================
Description:
	Sets up repeating timers without requiring any SetTimers and arranges them
	so that they will be very unlikely to meet (at least for a long time) using
	scheduling algorithms to get timers with the same period to be offset.  Also
	fixes arrays and strings in timers so they can be passed properly.
