If you have submitted a patch and it's in "Waiting for author" state,
please aim to get it to "Needs review" state soon if you can, as
that's where people are most likely to be looking for things to
review.

I have pinged most threads that are in "Needs review" state and don't
apply, compile warning-free, or pass check-world.  I'll do some more
of that sort of thing, and I'll highlight a different set of patches
next week.
