I was wondering the same thing... Especially if you're not waiting for it to finish, how can you ever know if it is hung or not?

I've used Parallel::ForkManager in the past to spawn processes, but it also has a 'wait_all_children' function that will cause it to wait until all of the children processes are finished. In that case, you can have the child processes return a variable denoted that it completed successfully, errored, returned invalid results, etc.

Of course it depends on what you're trying to accomplish, but if you don't wait for the children to finish, I can't imagine that you'd know whether or not they ever really did finish.
