Hi Sanjay,

The 7 extra days you requested beyond the original 7-day merge vote have
now elapsed, and we have the requisite three binding +1s to merge.

I'll plan to merge this late tonight unless there are any vetoes in the
meantime.

Of course we can continue to discuss the design and improve the clarity of
the documentation after it's in trunk, and if there's some kind of bug I'll
treat it as highest priority even after the merge.

Thanks
-Todd
