It's also up to the submitter to keep track of their patches. If they
think one should be applied that hasn't been, they need to follow up on it.
The only way to scale here is to push as much work as possible to the
outer-most nodes.
It's just really hard to track stuff without feedback. You only flush
your queue very sproadicly, so some kind of indicator that it is in the
queue would be extremly helpful. Just an ok, I'll queue it to mean that
it's not lost means we know it's been deal with in some way, and we can
ping patches that haven't gotten any feedback for say a week.
