	pluggable scheduler interface. Its configuration made a table
	of available schedulers and set a pointer to one of the.
	This was heavy handed since you can only use one scheduler
	in an application. This configuration mechanism resulted in a
	scheduler pointer being passed around when you could put all
	scheduler configuration in an initialized structure.
