You can say that again! I tried it with 2M test hashes. Without this 
patch, just _loading_ them took 47 seconds, then the c/s was reported as 
31200M (even though the initial loading time does not affect the c/s 
figure).

With the patch, loading them took about 2 seconds, after which it 
completed inc:digits in about 39 seconds (still 6 seconds before the 
unpatched version even had started cracking!). And speed was reported as 
5698005M c/s...

...speaking of that, I enclose a patch that make John say 5698G c/s 
instead (it's from fullMPI), is there any reason not to include this in 
the Jumbo?
