ListView performance becomes quite obvious when you run metacity. I can
see it redraw on expose (quickly, but I can still see it happening). So
if it's up to me: please do so!

As a side note: what setup are you using to profile banshee? Mind
sharing that? Previous attempts of mine to profile banshee resulted in
horrible crashes (admittedly, those are a very long time ago, mono has
improved a lot since).

Kind regards,
