$? is a variable that holds the return code of the last system command, pipes, ..., pretty much the same as in the shell. By inspecting that you can check if your command succeded or not.
As for your 'hellow' script, your user might have the path to it in it's environment. But the user the webserver is running as (www) most probably doesn't. So it's always a good idea to use the absolute path, and ensure that the user 'www' has read & execute rights on the file. If you still have problems, add the 'holy trinity' to your script, and run it on the command line.
Code:
# The 'holy trinity'
use strict;
use warnings;
use diagnostics;
As for Perl spinning out of control: it might have to do with the unchecked open. I left out the success check in my examples for brevity, but you should always check the return code of it.
