I don't remember if the OP specified *where* the scripted application is to
be run. If on a server, then *any* language with loops is vulnerable to
malicious users. If on a person's own desktop machine, where one can run
'diskformat' or the equivalent, or pick up and drop the machine, then
worrying about Python security seems superfluous. Why worry, for instance,
about os.unlink when the user can just do the same much easier in a text or
