2 - If you configured Tor to use bridge A, and then quit and
3 configured Tor to use bridge B instead, it would happily continue
4 to use bridge A if it's still reachable. While this behavior is
5 a feature if your goal is connectivity, in some scenarios it's a
6 dangerous bug. Bugfix on Tor 0.2.0.1-alpha; fixes bug 2511.
