  spawn more pack file helpers again now that leaks got fixed
  
  /usr/src updates have become slower for some reason and my best
  guess is that caching of packed data has become less effective
  with df613bb4d8662c28a9888714a80ca572bff9d924 (leaks were
  subsequently fixed by 2cb49fa8fb84f3a8fc2eb6036a6bd9b64c57e347
  and by 0dd5271bd8f2a4f92ac3536fcc493eebc39b86e5)
