I'd like, from within Ruby, to be able to:

1. Start a process/script
2. Stop a process/script
3. Monitor a process/script to see if it dies or is abnormally
terminated

I was expecting something like:

my_script = Process.new("/tmp/script.sh")
my_script.start

Essentially is there a way to create an object which is a system
process as you might with Java?
