NSUserDefaults as being thread safe. The NSUserDefaults page, on

Either way, is it safe for me to read user defaults in one thread,
while another might be writing? Or do I risk getting garbage back
from the reading thread?
Huh. I'm not sure why that warning's there. It should be thread-safe.
If you're reading from one thread & writing from another, one should
be blocked on the other. You shouldn't get garbage back.
That having been said: We fixed some thread-safety issues in Tiger -
I know there was a crash window in releases earlier than Tiger.
