Um, did you read the discussion of the ARC buffer management algorithm
that's already been implemented for 7.5?

The main objection I have to doing it Oracle's way is that that creates
more parameters that DBAs have to get right for reasonable performance.
Self-tuning algorithms are better, when available.
