Lock-per-Fqn option in addition to lock striping, for MVCC
----------------------------------------------------------

                 Key: JBCACHE-1494
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1494
             Project: JBoss Cache
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Locking
    Affects Versions: 3.0.3.GA
            Reporter: Manik Surtani
            Assignee: Manik Surtani
             Fix For: 3.1.0.GA


Lock striping, while performant and memory efficient, can lead to deadlocks in certain cases where several fqns map to the same lock.  An alternative where a lock er fqn is used may be desirable.
