Well, FWIW, I've been doing my very best to break threaded NSUserDefaults, and haven't succeeded yet. I've been running multiple threads with tight loops that read and write bunches of junk to NSUserDefaults, and it seems to handle them just fine. I only have a single processor machine - I guess there could be some subtlety that might crop up on dual processors, and AppKit wasn't doing much in the background with my test app, but it appears to work so far.

None of which proves much, unfortunately. Would be nice to get a definitive Apple answer on this...
I believe the official answer is "NSUserDefaults became thread-safe in 10.4".
