I pulled this, but then looked at the patch, and decided to unpull it.

The crazy "__nocapture()" annotations are too ugly to live, and make
no sense. They are basically random noise to some very core header
files. And the "__unverified_nocapture()" ones are worse.

I'm not sure how to fix this issue.
