Can you offer any advice for the times when I must write my own 
accessor, but want it to have similar behaviors to the autogenerated 
accessor? In particular, I'm thinking about the default atomic 
behavior. Is this simply wrapping the work in a @synchronized(self) 
block? Something else?

I'd look in the objc-2 sources, but they aren't available yet :-)
