The difficulty was getting my mapped result set back into a hashref that I could return at the end of the function, after all my child processes finished. I wound up "re agglomerating" my hash by storing the results of each function call on the hard drive with DBM::Deep.
I wound up needing to use a separate DBM::Deep file for each element of the hash, as I was unable to do this with a single DBM::Deep file, although I attempted to take advantage of locking support.
I wonder if there are other ways, including perhaps your previous suggestion to use ipc open3, perhaps bypassing having to store stuff on the hard drive completely. to be continued...
