Actually, this is the most common method of accelerating the calc... 
I don't think it freezes it. :)  There is still a _very_ small 
capacitance, simply because the traces are still there, and this 
results in a very high frequency (from what I have heard, about 3 to 
3.5 times faster).  And even if the capacitance went to absolute 
zero, the frequency would theoretically become infinite.  Wouldn't 
that be neat? :)  (Of course, the circuitry wouldn't be able to 
handle it...).
