So the grid instantly cools, all leakage currents or arcs to 
the anode vanish, and the grid remains at zero volts at the 
instant of grid opening.

Is that what you are proposing?.

Never mind, I probably did a poor job of explaining 
something very simple and we will have to agree to disagree. 
Repeating it five more times won't make any difference to 
anyone. People either get it, or they don't.
