Message 71045 - Python tracker

I was thinking about this on the way home last night and concluded that 
my last suggestion (s/0.0.0.0/127.0.0.1/) is a terrible one as well.  
I'd be happy with a mention in the documentation (for now) stating that 
if you listen on '0.0.0.0', Listener._address won't be a connectable 
end-point (and you'll have to explicitly connect to 127.0.0.1, for 
example).

As for the original issue, Jesse I'm +1 on your connection_v2.patch.
