Um, at least by my understanding, the use of Pickle is also dangerous if 
you are not completely sure what is being passed in:

   Warning: The pickle module is not intended to be secure
   against erroneous or maliciously constructed data. Never
   unpickle data received from an untrusted or unauthenticated
   source.
