I understand that there's *some* overhead associated with spawning a new thread, but from my impression it's not substantial enough to make a significant impact in most cases. Each individual instance of threading.Thread is only 64 bytes. Have you seen any recent cases where the server memory is limited enough for the memory cost associated with having to spawn an additional thread per subprocess becomes the limiting factor?
