You are a man of few words! Let me see if I understand this correctly. When I do '$pm->start and next', it forks a child which takes the first argument of the @command array and starts executing. At the same time, without waiting for the 1st child to finish, it forks another child that processes the 2nd argument of the array and so on, until 20 children are running in parallel. If 20 children already running, but there are still unprocessed elements in the array, it would wait until a child would finish and fork another child. The array is processed by children only, the parent doesn't go through the array. Is that about right?
Thanks much.
