public class FairBlockingQueue<E> extends Object implements BlockingQueue<E>
A simple implementation of a blocking queue with fairness waiting. invocations to method poll(...) will get handed out in the order they were received. Locking is fine grained, a shared lock is only used during the first level of contention, waiting is done in a lock per thread basis so that order is guaranteed once the thread goes into a suspended monitor state.
Not all of the methods of the BlockingQueue are implemented.
