On to your question. The Proc::Simple documentation says this about the exit_status() method:
"Returns the exit status of the process as the $! variable indicates. If the process is still running, undef is returned."
You can read about $! in perlvar - Error Variables.
You'll need to look at the child processes you're forking for answers as to why they're exiting with -1.
