So, after this got checked in I found an error, my track record with mock 
patches doesn't seem to be very good :)  So config['basedir'] doesn't actually 
have anything to do with self.basedir in Root(), it needs to be config['root'] 
that gets stuff appended to it and then self.basedir gets set from that.  My 
bad.  I've checking in the fix which (actually) works, hope that's OK.
