I think it might be time to revisit this issue. SR is in, and we have
a week left in the CF, and we have all of the above patches plus 5
small ones left to deal with. rbtree is close to being committable, I
think; knngist has not been reviewed yet; you (Tom) have claimed the
frame options patch but I haven't seen any update on it in a while; I
doubt either of the other two are ready to commit but I'm not sure how
far they have to go.

Thoughts?
