Description peavo 2015-11-18 07:29:24 PST 
This happens because the main thread is waiting for the sample scheduler thread to finish, but sometimes it never does.
This can be resolved by emptying the scheduler's sample queue before requesting the scheduler thread to finish.
This will make sure the scheduler thread returns to it's main loop quickly, and can handle the termination request.
