It would be difficult to put in a single priority/nice value that was
meaningful, without adding complexity to the clock interrupt code.
Just recording the nice value at a single instant (probably process
termination) isn't reasonable.  A process doesn't deserve a discount
because it ends with:

		nice(20);
		exit(0);
