I have a java.util.concurrent.LinkedBlockingQueue<Step>() which holds every step for my build pipeline. I also have a variable count of workers that call a getWork() method to get one of those steps. getWork() looks like:

Step getWork() {
  if (Data.stepQueue.size() == 0) {
    return null
  }

  Step work
  try {
    timeout(time: 10, unit: 'SECONDS') {
      work = Data.stepQueue.take()
    }
  } catch (e) {
    echo "Pipeline Warning: Could not take new element of stepQueue. Worker may shut down now..."
    return null
  }

  if (!work.readyToRun) {
    Data.stepQueue.put(work)
    return getWork()
  }
  return work
}

I put a timeout around the take() call, because there might not be enough work at the end. The issue is, that killing this takes much longer than it should.

I checked the source code and there is already a forcible attribute. It would be great to pass a value by calling timeout like this:

timeout(forcible: true, time: 10, unit: 'SECONDS') {
  data.take()
}

Please add the possibility to enforce this.
