By directly shorting a charged pulse-duty capacitor, severe stresses are 
imposed as tens of thousands of instantaneous amperes are flowing.  If you 
feel absolutely compelled to place a safety gap across the capacitor, you 
should also place a high voltage power resistor in series with the gap.  To 
do otherwise could have equally detrimental effects on your caps as 
overvoltage.

But Kreso doesn't use sfety gaps - they limit the amount of destruction 
possible....
