A couple of questions about your code:

  1. Why accumulate your thread handles into @kids when you never use them again?
  2. Why not detach the threads at creation when you don't use the returns?

Please note. There is no implied critism here, just comparing notes.

FWIW, I like your technique of enqueuing undefs to terminate your loops. It's much cleaner than several things I've used.
