Have you trying using the pessimistic locking scheme? 

Try adding the following to your replSync-service.xml:
<attribute name="NodeLockingScheme">PESSIMISTIC</attribute>
  |       <attribute name="SyncCommitPhase">true</attribute>
  |       <attribute name="SyncRollbackPhase">true</attribute>      
  |       <attribute name="IsolationLevel">SERIALIZABLE</attribute>

It is the only way i have found to have "select for update" semantics (blocking reads), and it is deprecated.. See my post on a comparable topic: [url]http://www.jboss.org/index.html?

I have no clue how to achieve the same thing with MVCC (or even if it is possible at all)
