# TODO(jhylton): Should this be redesigned to handle
        # persistent connections?

        # We want to make an HTTP/1.1 request, but the addinfourl
        # class isn't prepared to deal with a persistent connection.
        # It will try to read all remaining data from the socket,
        # which will block while the server waits for the next request.
        # So make sure the connection gets closed after the (only)
        # request.
        headers["Connection"] = "close"

this has been a long time..how many is annoyed by this..Count me in..
persistent connections may not be easy on various OS and act the same.
I'm just satisfied if it works on linux.
