Parallel::ForkManager has a mechanism for sending data back to the parent from the child processes as of version 0.7.6, which sounds like what you are really wanting to do. (There is a section of the documentation on it, as well as an example. Adapting the example was not, in my experience, a difficult exercise.)

Hope that helps.
