Comment(by atagar):

 > The is_alive() method is broken when a controller issues a "QUIT"
 message.

 Hm, that does seem like a bug. I'll look into it a bit tomorrow and add a
 test for it - not sure what's happening there yet.

 The controller's is_alive() method *should* behave the way that you want,
 and it's a bug that it doesn't. We shouldn't need to actively query tor to
 make this work, though.

 > We can use a sample PROTOCOLINFO query to check - it doesn't need auth,
 so it won't close the connection

 Funny thing about PROTOCOLINFO, it *does* disconnect the socket if you
 issue it more than once before authenticating. Personally I think that's
 stupid (and had to hack around it in the connection module), but oh well.
