It's an improvement but for numbers around 10^10,000,000 you still need a 
table with O(10^5,000,000) entries ... not very practical when computers have 
not much more than 10^12 table entries to play with.

I'm afraid lots of people - including many with mathematical backgrounds - 
simply don't have much idea about the vastness of the numbers we're actively 
engaged in testing.
