If you have the Oops output, that's always nice to put in the commit
message.

Why don't you set the pointers to NULL in stub_shutdown_connection()
since that's where you actually kill the threads. Setting them to
NULL in stub_device_reset() will (sometimes) solve the problem but
it gives you a new problem of a resource leak.
