It does this because the debug loop happens in a different thread, and it wanted to ensure that the process plugin cannot be killed before we've cleaned up gracefully.

I would change it to a std::weak_ptr if possible. That way if the plug-in goes away, you will try to lock the weak pointer and notice the shared pointer is NULL and know the process is gone and you can proceed to shut down this extra thread.
