I'm not going to try to audit for that exhaustively right now, but I've 
changed all the calls to fail that were broken by the Either change, so 
hopefully we should be back where we started.

I've put a repo up with the changes and a base dependency bump at 
http://urchin.earth.li/git/HTTP - could you (and anyone else interested) 
give it a try? I haven't done anything but the most minimal testing and in 
particular I haven't made any effort to reproduce your specific problem.

I plan to upload this as HTTP-4000.0.10 in the next few days.
