Hmm... This may be a bug somehwere, I'll have to take a look at it. But,
all of this information is available directly without having to use
subprocess_env, as part of the request object or req.headers_in.
Subprocess_env is an inefficient way of doing it since it is artificially
constructed from the same sources to which mod_python allows you direct
