title: Pycharm debugger when using multiprocessing pool
body: <p>My problem is happening with this setup :</p>
  <ul>
  <li>Pycharm 2020.3 pro</li>
  <li>multiprocessing.Pool</li>
  <li>Macbook pro 2020 (M1)</li>
  <li>Conda python 3.8</li>
  </ul>
  <p>And most of all, it happens when I use the debugger of pycharm.</p>
  <p>It shows 8 times (number of processes) in the console :<br />
  <code>Error loading: /Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/pydevd_attach_to_process/attach_x86_64.dylib</code></p>
  <p>Every processes are executed. Results are correct. I can see them with htop command. So it's only a debugger failure and doesn't really impact code execution (correct me if I am wrong).</p>
  <p>This is the kind of code I run :</p>
  <pre><code>def func(x):
      return x+10
  
  
  if __name__ == '__main__':
      poo = Pool()
      x = [[i] for i in range(10)]
      res = poo.starmap(func, x)
      print(res)
  </code></pre>
  <p>I can ignore for now those massive printing in my console but it's not really convenient. If someone has an idea to get rid of those...</p>
