I think the only reason it didn't get merged was because Tomasz didn't
post out the next version of the patch, with the feedback received for
v1.

I know that Tomasz has moved away from working on this area, so if
you'd like to, please feel free to submit an updated/rebased version
for review.

If you wouldn't like to do that for any reason, please let me know,
and I could cook it up instead.
