Control TCP Socket not created under some circumstances
I had to set ControlPort to get tor to open a control socket for TCP. Setting ControlListenAddress to e.g. 10.0.1.140:12345 does not suffice.
Additionally, I had to configure any kind of authentication method. The Documentation does not state, that authentication must be used to get a control socket. It actually says, that no authentication will be used unless it is configured explicitly.
I am using version v0.2.3.8-alpha with git commit id git-68475fc5c5a806eb.
