I don't know how useful Windows numbers will be, since Windows timeouts 
are implemented differently, but Win64 is sort of unusual....

Windows Vista SP1, 64-bit, Intel Q9450, native 64-bit: 66.  I also ran a 
32-bit Gambit executable under WOW64 on the same system and got the same 

In comparison, an extremely un-unusual Windows XP SP3 on a Intel T7250 
yielded 65.
