kAudioDevicePropertyStreamFormat notification

In which context do I get the kAudioDevicePropertyStreamFormat property listener callout, in the UI thread or the RT-thread?

What can cause this notification? The user or some other application?

Does CoreAudio stop the IOProc:ing when it decides the stream format has changed, or does it merrily continue to be called? The reason I'm asking is that we might have auxiliary data used in the IOProc, If the notification comes in the UI thread I'd have to develop synchronization means. I'd rather not.

Cheers,
Markus
