I believe that 'diminishing returns' does happen, _if_ you take a static engine
and run it on faster and faster hardware.  But if you continually update the
engine/evaluation/search as it is tested on faster hardware, I don't see
anything (yet) that says that once we reach depth D, going deeper will not
make the program play any better...
