This sounded very much like some lock-free concurrency models I'm  
interested in, so I did a google search and came up with a document  
that will probably do a better job of explaining it than I could:

The interesting thing about this to me is that these features are  
being added to programming languages, which gives a much nicer and  
more flexible model for handling data synchronization among  
concurrent processes.
