Its more complex than that IMO.

Consider sftp:

file_handle = a_transport.get_file('foo')
a_transport.close()
file_handle.read()

In other words, because transport returns objects that depend on the
transport, closing a transport may be inherently flakey.

I'd like us to put some use cases for disconnecting together, and then
we can plan how it should work.
