* to clean up things), so the main loop will never regain control off
* the app.
*
* . we can't access the internal vmtoolsd functions that cleanly shuts
* down plugins.
*
* So, right now, let's stick with just stopping the RPC channel so that
* the host is notified the application is gone. This may cause temporary
* issues with clients that only look at capabilities and not at the
