Comment (by rl1987):

 One more pull request for diagnostics:
 https://github.com/torproject/tor/pull/560
 * This time, let's use `getsockopt()` to check if new listener is actually
 listening.
 * Let's log some stuff when socket rebinding is supposed to happen.
 * Let's log the proper error message when `socket.connect_ex()` fails on
 Python side.
