Problem is, and it's the same when forking, that the parent can't see @out. Should I move the $out[$i] .= $_; to the parent process? The forked processes work fine, and fairly quickly, but I need to get the child to tell the parent what it found.

I'd rather not have to use the temp file solution, as it will get very messy when having multiple users run multiple processes at the same time. That's going to make this whole process run a lot slower. I'd rather see if I can find a solution that passes data faster back to the main process.
