Subject: change bind_unused_port to pass None as port
X-Git-Tag: v3.1.0~76^2~19^2

change bind_unused_port to pass None as port

bind_unused_port was passing 0 as port number to the socket module.
This generated some exceptional behaviour on systems where nslookup of
localhost didn't returned the loopback interface.
