Upstream: disable body cleanup with preserve_output (ticket #1565). With u->conf->preserve_output set the request body file might be used after the response header is sent, so avoid cleaning it. (Normally this is not a problem as u->conf->preserve_output is only set with r->request_body_no_buffering, but the request body might be already written to a file in a different context.)
