.NET 4 includes new concurrent data structures. The Bag and Dictionary collections have obvious applications but I cannot see any use for the Queue and Stack data structures. What are people using these for?

Also, I've noticed that the design based upon linked lists incurs a lot of allocation and that destroys scalability. This is surprising given that the sole purpose of these collections is multicore programming. Is this an inherent limitation or are they just badly implemented?
