* This implementation employs elimination and combination to transfer elements between threads that
* are pushing and popping concurrently. This technique avoids contention on the stack by attempting
* to cancel opposing operations and merge additive operations if an immediate update to the stack
* is not successful. When a pair of operations collide, the task of performing the combined set of
* operations is delegated to one of the threads and the other thread optionally waits for its
* operation to be completed. This decision of whether to wait for completion is determined by
* constructing either a <em>linearizable</em> or <em>optimistic</em> stack.

* Iterators are <i>weakly consistent</i>, returning elements reflecting the state of the stack at
