I'm disappointed that kThreadPriority_RealtimeAudio snuck in here. This is
really violating layering boundaries. PlatformThread should provide a audio
agnostic API for controlling priority. I see Darin made the same comment
previously.

You don't have to fix it here, but I just wanted to point out that I too dislike
this.
