This is interesting, though I have not taken the time to think through the implications the fact that this is costing us so much is interesting in itself.
While folks debate the pluses and minuses of various tacks on the problem, I am willing to run a rigorous performance analysis against the head if you'll post a patch. Even if the patch is crude and does not capture the correct fix to the problem, measuring it really exhaustively across dacapo may help inform the discussion. I'll analyze it across all of dacapo in a controlled environment.
