If the third argument is true, sys.path is modified to include
       either the directory containing the script named by argv[0], or
       the current working directory.  This can be risky; if you run
       an application embedding Python in a directory controlled by
       someone else, attackers could put a Trojan-horse module in the
       directory (say, a file named os.py) that your application would
       then import and run.
