RegionManager region map should be ConcurrentReaderHashMap
----------------------------------------------------------

                 Key: JBCACHE-826
                 URL: http://jira.jboss.com/jira/browse/JBCACHE-826
             Project: JBoss Cache
          Issue Type: Task
      Security Level: Public (Everyone can see)
            Reporter: Brian Stansberry
         Assigned To: Brian Stansberry
            Priority: Minor
             Fix For: 2.0.0.GA


The regionMap in o.j.c.eviction.RegionManager is a Collections.synchronizedMap.  This should be a ConcurrentReaderHashMap.  If eviction is used, for every call the EvictionInterceptor makes a call that ends up doing a lookup in this map, so the synchronization becomes a choke point.

I already made this change in HEAD along with some refactoring work on eviction configuration.
