That patch is not necessary on master, you want it for the patch branch?
Why is it building the native extension at all? Our patch should disable it and use the pure python impl. I even upstreamed that patch.

Ah, sorry, hadn't seen your upstreamed patch. In that case let's sit this out and tell people to pick newer pymongo when it's there.
