 FreeBSD jails or some OpenVZ virtual machines do not have a `lo` interace
 (no 127.0.0.1 or localhost address), they only have an interface with
 either a public IP address either a NAT address routed upstream on the
 host.

 In this case, if ControlPort 9051 is set, it will open the control port on
 the public IP address without even a warning which is not funny. This
 applies also to SocksPort, but that's less scary than ControlPort.
