- Add tests for the module-level load() and dump() functions. - Add tests for cPickle's internal data structures, stressing workloads with many gets/puts. - Add tests for the Pickler and Unpickler classes, in particular the memo attribute. - test_xpickle is extended to test backwards compatibility with Python 2.4, 2.5 and 2.6 by round-tripping pickled objects through a worker process. This is guarded with a regrtest -u xpickle resource.
