It appears that join() is never actually called in Transport.stop_thread()

As part of my investigation into #2184, I figured it would probably be worthwhile to look around the paramiko package to get an understanding for how it works / what might be happening.

Something that stood out to me was, as mentioned in the title, it appears that join() is never actually called in Transport.stop_thread().

See my comment here:

I only noticed this when reading over the code, I don't know if this is actually related to the crash I'm seeing. bskinn suggested that I submit a new issue on this topic.

Thanks for the report, @ni-balexand!
