@Override

    // We're not calling triggerExecutorIfNeeded here after the inser. The unacquire happened
    // for a reason (eg queue full or exclusive lock failure). No need to try it immediately again,
    // as the chance of failure will be high.
    
  } else {
    // It could be a v5 job, so simply unlock it.
