LOL!  It's a small world, eh?

I had not done more testing since the socket.shutdown() was added.
Now I have tested and I no longer have TOR connections hanging.  Thank
you.

As long as the socket error is local, then None is returned.  I was
concerned about remote (silent) errors going undetected.  But, further
tests (e.g. 10 minute timeout) also did not work on a long-running
client listening for TOR events.  I now believe that absent a defined
keep-alive framework in the control protocol, it is best for any
client which cares to check the connection status to periodically run
a small query (i.e. "GETINFO version") and check for a response.
