MusicEventIterator questions

I have a couple of questions regarding MusicEventIterators.

Can they be used in the render callback? It would seem like the answer to this question is no as I'm pretty sure that the call to NewMusicEventIterator will most probably allocate memory.

Also in the doco it states:

"If you edit a music track after associating it with a music event iterator, you must discard iterator and create a new one."

If you were using MusicTracks to store note and controller information what is the situation with thread safety of the MusicEventIterator when used in a producer consumer type fashion. When using multiple threads I have the possibility that the MusicTrack will be edited while I am iterating. Will this throw an exception or will I just be iterating over stale information?
