Some time ago, I was thinking about creating such second-pass search.
I even have some ideas that could make second pass _better_ than the
first, because we already know (more or less, but we do) future motion
vectors (those down or right of current macroblock). I even already
know how to re-decide about inter4v quite quickly (well based on my
code which makes 4xsad8)
