This is from Zombie's, copy and replace this over Zombie's judge.php
You can set the time-out from the GUI.
VERY important, that I found out the hard way:
since your script is being included (and not executed as the real contest will be done), do NOT use global in your functions, as that looks for global variables in judge.php's global scope and NOT your capture.php's global scope.
