Here is the patch in its "final" state after my minor additions, edits and
review.

Performance tests for me show that the patch is effective; my results match
Jesper's roughly in relative numbers.

My robustness review is that the approach and implementation are safe.

It's clear there are various additional tuning opportunities, but the
objective of the current patch to improve performance is very, very clearly
met, so I'm aiming to commit *this* patch soon.
