Uh, I practically know nothing about the performance impact of virtual
methods. But as you say yourself, compared to the actual work the method
does, it would not matter much. So if there's no way to avoid them, I
believe we can easily live with them :). To be frank, I don't expect to
be able to play v0.4 on my old P200. And I do not mind if it uses 30%
CPU on my Athlon instead of 27%.

That aside, the example works flawless. Cool!
