The easiest approach:

	starter = 'ruby test.rb'
	pid = spawn starter
	Process::waitpid2 pid		# if you want to wait on the process to finish

or if yo want more flexibility:

	starter = %w{ruby test.rb}
	exec *starter unless pid = fork

There's a brief write-up of both spawn and exec in the "Ruby Plumber's  
Guide" presentations at the link in my sig.
