[paramiko] transport threads not shutting down

[Justin Cook]

After calling transport.close(), it appears the transport threads are
not stopping in a timely manner. Furthermore, the socket module is
being destroyed before the thread stops / exits. Obviously this is at
interpreter shutdown. Sometimes I receive the following exception at
program exit:

Original exception was:

Am I missing something?
