title: Python multiprocessing - check status of each processes
body: <p>I wonder if it is possible to check how long of each processes take.<br>
  for example, there are four workers and the job should take no more than 10 seconds, but one of worker take more than 10 seconds.Is there way to raise a alert after 10 seconds and before process finish the job. <br>
  My initial thought is using manager, but it seems I have wait till process finished.<br>
  Many thanks. </p>
