Personally, I anticipate using shared for large global containers almost 
exclusively.  I've never considered the "interconnected web of shared 
objects" idea to be a good one, and building shared into the language 
doesn't change that.  For containers, a range returned by a shared 
container will probably have to hold the lock on that container until it 
is destroyed or shared won't be terribly useful.  I haven't thought 
about this very thoroughly, but that's my initial take on the idea.
