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?
