[New-bugs-announce] [issue5665] Add more pickling tests

[Collin Winter]

New submission from Collin Winter <collinw at gmail.com>:

The attached patch adds more tests for pickling:
- 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. 2.3 was too difficult to support.

I'll port to py3k after reviewed for trunk.
