I don't see anything wrong with it and it's passing my tests, but we've got a handful of ways to boot so it's all a bit messy and I might be messing something.
I'm still catching up a bit as I took both days off this weekend. Hopefully just an oversight in a bigger rafactoring, but I'll give it another look.
Marc: are you going to send that as a patch?
