I have come up with a class called SafeString which is the opposite of a tainted string. In my model, all strings are tainted by default, and you have to call untaint() to create a SafeString. Then I replace all functions in the os module with wrapper functions that check all parameters first and raise TaintError if any string is not safe. If I can figure out how to attach a file here, I will post it. Otherwise you may find it on comp.lang.python by the name of taint.py.
