Some middlewares require the Rack env to be preserved all the way through to close, so we'll ensure all request models preserve it. We also need to better response body wrappers/proxies always get fired properly when returning. IO.copy_stream and "sendfile" gem users could hit cases where wrappers did not fire properly.
