Just the opposite!!  People use WHOLE systems, so a benchmark that
loads the WHOLE system IS a very usefull benchmark!!!

before you flame, note:  I agree that a loop like
	for ( i=start; i<end; i+=big ) {
		sum += array[i];
	}
would NOT be very useful, but 50-500 lines of code that includes
computaion and frequent, random accesses to an array of several
megabytes would be GOOD
