So seems like many people have been hacking in private on this one. It
is good that people are interested, bad that it is coming up now. We
need to get a 3.5 out the door and right now my time is better spent
looking at issues related to and getting ready for a release of that.
These patches/work items will get a look in good time, but for now,
they are simmering and waiting for 3.6.X development to start (updated
