	   statistics call cyg_cpuload_create()/cyg_cpuload_get()/
	   cyg_cpuload_delete(), with get() returning the load over a 0.1s, 1s, 
	   and 10s interval.  The only one of these capabilities that's even 
	   potentially usable is cyg_cpuload_calibrate() and even that's rather 
	   dubious for general use since it runs a thread at the highest priority 
	   level for 0.1s for calibration purposes and measures the elapsed tick 
	   count, which will hardly endear us to other threads in the system.  
	   It's really meant for development-mode load measurements and can't 
	   safely be used as an entropy source */
