Would either Parallel::ForkManager or Schedule::Parallel be of assistance? While I lack in experience with the latter, my experience with the former has (so far) been that the jobs (code) are loaded into the queue, and N items are run, with the next job in the queue being run when another completes. Because they are child processes, they inherit the open filehandles, iirc.
