Option for fair locking in MVCC
-------------------------------

                 Key: JBCACHE-1498
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1498
             Project: JBoss Cache
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Locking
    Affects Versions: 3.0.3.GA
            Reporter: Krzysztof Sobolewski
            Assignee: Manik Surtani
         Attachments: fair-locking.patch

The javadoc for OwnableReentrantLock says:
 * For the sake of performance, this lock only supports nonfair queueing.
Well, I understand the sentiment, but starvation can be quite a problem with nonfair locking. So I implemented an option to swith to fair locking (patch attached).
Please review :)
