This qualifier allows setting the detection level after which
 	ecoapp will cease activity. This level is given as a floating
 	point number, and is compared against the current one minute
 	system load. If the system load is higher than the specified
 	level then ecoapp will cease waiting for interrupts, which
 	will lead to higher physical cpu consumption, but also to a
 	more efficient processing due to the lack of waits, context
 	switches and cache invalidations. If the system load drops
 	below the level	the ecoapp will start to use wait cycles again.

 	Example: ECO SET/LEVEL=1.5 will caese activity if the one
 	minute system load will raise above 1.5.
