    >> 1) SocketConnectionError

I like the fact that we will differentiate between various
connection related errors. But I think in that case
OpenConnectionError may be more appropriate (port is always
related to socket no ?).

There are some other places that will need fixing in other
transports. It seems to be mostly hhtp ones so I can handle that
once your patch is merged (and mines too :).

+1 (if renamed OpenConnectionError or something else related to
    initial use of the socket)
