Async marshalling, async cache loading  and async notification handling use unbounded queues
--------------------------------------------------------------------------------------------

                 Key: JBCACHE-1443
                 URL: https://jira.jboss.org/jira/browse/JBCACHE-1443
             Project: JBoss Cache
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: 3.0.0.CR3
            Reporter: Brian Stansberry
            Assignee: Manik Surtani
            Priority: Critical
             Fix For: 3.0.0.GA


The async handling in CommandAwareRpcDispatcher, AsyncCacheLoader and NotifierImpl all use Executors.newFixedThreadPool() so set up their ExecutorService.  Per the method javadoc for that method "Creates a thread pool that reuses a fixed set of threads operating off a shared unbounded queue".  Use of an unbounded queue is inherently unsafe, and particularly in these use cases where there could be a very large number of threads adding tasks to the queue, while the default config only creates a single thread to take tasks off the queue.
