 * A {@link BlockingDeque} which forwards all its method calls to another {@code BlockingDeque}.

 * asynchronous operations. You can chain them together manually with calls to methods like {@link
 * Futures#transform(ListenableFuture, com.google.common.base.Function, Executor) Futures.transform}
 * (or {@link FluentFuture#transform(com.google.common.base.Function, Executor)

 * when the expected present count is correct.
