[concurrency-interest] PriorityBlockingQueue uses a fair lock

A colleague noticed that PriorityBlockingQueue's
internal lock is a fair ReentrantLock,
when a non-fair lock would be much faster
and usually "fair" enough.  Is there some history here?
Should we add a non-fair option for constructing PBQ?
