The tricky thing about DFS is that a fix for one person can easily cause
failure for another. The solution will be to look really closely at the
semantics of paths and path components in the DFS referral messages. I
can't just tack on a slash and hope for the best.

I'll add this to The List (actually I think I added this to The List
before but it could be independantly important).
