Investigate making HASingleton failover "stopOldMaster" RPC synchronous
-----------------------------------------------------------------------

                 Key: JBAS-7999
                 URL: https://jira.jboss.org/jira/browse/JBAS-7999
             Project: JBoss Application Server
          Issue Type: Task

          Components: Clustering

When a node becomes master, it tells any previous master to stop. That call is async, probably because long ago this was done on a JGroups up thread and making a sync call from that up thread would hang. This is no longer done on an up thread, so investigate adding a config option to allow is call to go synchronous, thus ensuring the old master is fully stopped before new one starts.
