Beautiful analogy - puts this thing to rest in my mind, 'cuz I know 
that a radiator still works in fast cars as well as tractors.

Maybe it would ease some minds not to think of cavitation, but just 
turbulent flow?  I could envision that it may not be cavitation 
causing lack of hot metal to coolant contact, but turbulent flow in 
the coolant passages that causes loss of contact?
