<sigh>  Yeah, that's because you've got some kind of unrecoverable
network error, and the default httplib doesn't handle.  Fortunately,
because you're using httplib directly (instead of urllib), you can
modify HTTP.sock to have a timeout (assuming you're on a platform that
supports it).

The code looks more-or-less like:

HTTP.sock.setsockopt(socket.SOL_SOCKET, socket.SO_RCVTIMEO, timeout_ms)
