Will I be in a pickle?

[Ken Seehof]

The documentation warns that unpickling from an untrusted socket is dangerous,
and also tells how to use find_global to protect myself.  I understand how one
would hack a naked pickle destination.

Can anyone confirm whether or not it is actually safe and secure to use cPickle
if I use find_global to restrict the data to a specific set of a few classes?

Can anyone give an example of a hack against the above scenario?
