Research direction

Start with the urllib2.urlopen entry point and reproduce the failure described when http_proxy or https_proxy is set to a SOCKS5 proxy under Python 2.7. The payload names no source file or test; completion would require a confirmed behavior change and a regression check for the proxy case.
