It compiles, the same is confirmed even with latest Head.
Can you please point me if you feel something is done wrong in the patch.

The WIP word is from original mail chain discussion. The current status is as follows:
I have update the patch with all bug fixes and performance results were posted. Noah has also taken the performance data.
He believes that there is discrepency in performance data, but actually the reason according to me is just the way I have posted the data.
Currently there is no clear feedback on which I can work, So I would be very thankfull to you if you can wait for some conclusion of the discussion.
With Regards,
Amit Kapila.
