You could run the judge as a background process, and kill it after ten
seconds if it hasn't finished.

You could run the judge from its own account that doesn't have access to
anything else. For extra security, make the judge program itself owned by
a separate account (but readable/executable by the judge account.)
I suppose you'd have to disable mail access from the judge account too.
Not sure how to easily do that.
