I have not looked through all of the code, but my thoughts at first glance were:

  1. look at Parallel::ForkManager for handling the forking, as it allows you to limit the number of forks, and newer versions allow you to pass data back to the parent easily, and
  2. as you appear to be looking initially at a CSV file, perhaps Text::CSV might make the field handling easier.

Hope that helps.
