First off, I love unicorn. Thanks to all who have worked on it. For the first time, I am trying to run a rails 2.3 app with unicorn. I don''t understand what is not set correctly.

I got rid of (a little less) than 1kB in camping.rb and removed lots of un-necessary files (lib/server/*.rb, fastcgi.rb & mongrel.rb). bin/camping does now only provide WEBrick, Mongrel and console-support and should only be used in development.
