> As described in http://wiki.jboss.org/wiki/Wiki.jsp?page=ProblemAndClusterRPCs the use of message bundling is not optimal for RPC calls.  Essentially all clustering traffic in the AS is RPC calls, so we should evaluate the impact of disabling message bundling.
> I'm going to evaluate this using both REPL_SYNC and REPL_ASYNC.  Any negative effect of bundling with REPL_ASYNC should be less, as the caller does not wait for the response.
