    Helper used to deal with submitting procs with nonce. Internally the NonceProcedureRunnable.run() will be called only if no one else registered the nonce. any Exception thrown by the run() method will be collected/handled and rethrown. long procId = MasterProcedureUtil.submitProcedure( new NonceProcedureRunnable(procExec, nonceGroup, nonce) { @Override public void run() { cpHost.preOperation(); submitProcedure(new MyProc()); cpHost.postOperation(); } });
    
    Throws:
    
    IOException
