I did grep and as far as I can tell only the old CGI and FastCGI 
adapters used it. That's why it's removed in my patch and replaced by 
CgiAdapter#process. It's a bit of a blend between the Mongrel handler 
and the original Cgi.process :)

As for the URI handling, I did experiment a bit with stripping the 
SCRIPT_NAME in the CGI adapter and redefining EncodeURI#encode_uri to 
add it again. This should work. I left it out because it still had some 
edge cases that didn't behave right. Maybe it could be added again. 
Either way some documentation on how to set up your server so this isn't 
necessary, or how to adapt Nitro if it is necessary would be good.
