Peter, I haven't tried this, but my knee-jerk reaction is to switch the roles of the "wait" and "success" relationships. Maybe you can send the "wait" relationship downstream and route the "success" one back to Wait. Then when the flag is "cleared", the flow files will start going to the "success" relationship which is routed back to wait.
