Jim Fulton:
- Loading non-binary string pickles checks for insecure strings. This is needed because cPickle (still) uses a restricted eval to parse non-binary string pickles. This change is needed to prevent untrusted pickles like:: "S'hello world'*2000000\012p0\012." from hosing an application. - User-defined types can now support unpickling without executing a constructor. The second value returned from __reduce__ can now be None, rather than an argument tuple. On unpickling, if the second value returned from __reduce__ during pickling was None, then rather than calling the first value returned from __reduce__, directly, the __basicnew__ method of the first value returned from __reduce__ is called without arguments.
