The Wait-Free Double-Ended Queue

The wait-free double-ended queue is just a class that composes a wait-free write queue with a wait-free read queue. This is strictly a convenience class. It offers no facilities that you would not get from the two separate components.

The correct use of a WaitFreeDequeue would be to have the higher-priority end of the double-ended queue use force, nonBlockingRead, and nonBlockingWrite. The lower-priority end of the double-ended queue should use blockingRead and blockingWrite.
