memo attribute of cPickle.Pickler objects is used by some third-party code. Jython could expose this attribute for compatibility with CPython.

$ python2.7 -c 'import cPickle, StringIO; print(cPickle.Pickler(StringIO.StringIO()).memo)'
{}
$ jython2.7 -c 'import cPickle, StringIO; print(cPickle.Pickler(StringIO.StringIO()).memo)'
