This is a rather poor test, not only because of the artificial nature
of the position, but also because such very long, forced mates doesn't
really measure anything else than the maximum search depth of a program.
My program has the maximum depth set to 60, and will therefore *never*
find the mate, even if you let it search for billions of years.  After
changing the maximum search depth to 100, mate is announced after 33
seconds (on an iMac G5 1.8 GHz).
