[mod_python] Translation handler help?

We're implementing a bunch of stuff on top of mod_python, and have avoided
using the
translation handler. Until today.

I'd like to rewrite the URI -- but req.uri is readonly. I can't find a
req.uri() method ...

I'd like to find the equivalent of the CGI document root -- but
apache.build_cgi_env() is not happy about running inside the transhandler():

File /usr/local/pythonpackages/mod_python/apache.py", line 189, in Dispatch
    result = object(self.req)
File "/usr/local/pythonpackages/phtml/phtml.py", line 14, in transhandler
    env = apache.build_cgi_env(req)
File "/usr/local/pythonpackages/mod_python/apache.py", line 418, in
build_cgi_env
    env[k] = req.subprocess_env[k]
KeyError: SCRIPT_FILENAME

Does anyone have a creative or even functional example of a translation
handler?
