Kirk,

 in the MI world, this annoying cycle hog is refered to as"the
governor"...kinda like a governor on a motor vehicle keeps it from going
beyond a set speed or rpm's by (generally) choking the carb...this just
pigs out on cycles until the sys load lowers...

Not to be confused with QSYSARB which is something else totally...
