There's a simpler way to do what you want. Just call
demuxer.work_started() before calling demuxer.run(), and then call
demuxer.work_finished() when you're ready to shut down.

These functions are provided to ensure that demuxer.run() does not exit
 when an asynchronous operation (the "work") is being carried out by
something external to the demuxer (such as a thread).

Fair enough. I'll leave them as separate for now.
