No they don't. To be clear, I'm talking about copying the container, not  
the values inside them, in a non-destructive manner. My data structures  
book and wikipedia make no mention of a .dup like method as being part of  
a container. I do agree .dup is useful and quite practical for serial  
containers, but it is by no means required. But you haven't answered the  
question of a value semantic lock-free container.
