If Python blocks in the SSL handshake it seems to be
completely uninterruptible, and I've been seeing it
block for at least hours recently. I don't know if the
problem is on the client side or the server side or
somewhere in the network, but setting the timeout
at least means you're guaranteed a new shell prompt
(after printing some errors).
