@mhoeber @lamagnifica @stephensanchez @wedaly @gradyward Please review. This is a draft so things may be a little rough around the edges, and I have a couple of notes to myself inline.
No problem a-tall. These changes are still pretty brand-spankin' new and I don't know if you even knew about our ORA2 sandbox. But yep, we fixed that messaging problem. :-)
