  1400 seconds? Well my CPU is a quad-core 3.2Ghz, but it's not 
using threading so...

  I have made a C version a while back that solves any sudoku 
puzzle in 1/8th of a second. The code for that though was 
considerably longer and involved several forms of pattern 
matching and detecting how to solve the puzzle before it went to 
brute force as a last resort.

  Give me about 30 minutes, I'm going to clean the code up since 
several parts of it do rely on single character variables. I'll 
also add a little documentation so the 187 lines will likely 
expand to about 200, if I add all the actual unittests I need 
likely 250 lines.
