It would really be a functional test, since the problem with half-open 
connection pile-up stems from smtp server's access control rules.

To test we should setup a fake smtp server, which forbids having multiple
connections from the same IP address, and connect twice in a row to the 
fake server. I'm not sure I'm able to implement both an smtpd.py server
serving more than one connection and the client code in a race-free way in 
the same "unit" test. Will try in the next week.

Thank you very much,
