It's not entirely clear to me what you're trying to do. However, I find Parallel::ForkManager useful for controlling how many jobs get spawned at once and IPC::ConcurrencyLimit handy for making sure that I don't run multiple copies of my scripts at the same time.

You can find examples of both in the scripts that keep cpXXXan up to date.
