+ * in PODC96 by Maged M. Michael and Michael L. Scott. Pseudocode is available here:
+ * http://www.cs.rochester.edu/research/synchronization/pseudocode/queues.html
+ *
+ * The implementation provides thread-safe \c push and \c try_pop operations, as well as
+ * a thread-unsafe \c empty operation. The queue imposes the following requirements
+ * on the element type:
+ *
+ * \li Default constructible, the default constructor must not throw.
+ * \li Copy constructible.
+ * \li Movable (i.e. there should be an efficient move assignment for this type).
+ *
+ * The last requirement is not mandatory but is crucial for decent performance.
