bring back in the other tests
aha, here's a bug.  after a failed connection due to a bad server
certificate, we seem to get stuck... maybe the server is busted
everything seems to work which is great.  there is one slight rub which
is that I can't seem to disable logging of Warnings in test_ssh, I think
due to some weird interaction between the unittest system and the
logging system.  maybe a racey condition?
