Trivial test for paramiko issue #22

This demonstrates issue #22. For this to expose the problem, you have to reconfigure your local sshd to listen only on a IPv4 socket. I had to add the following line to /etc/ssh/sshd_config (on a Debian system):

ListenAddress 0.0.0.0

With that change, paramiko can not connect to localhost anymore:
