One thing that might be worthwhile is to move the MUCH_RING_CHECKING code
from cPickleCache.c into a common file, and use it in cPersistence.c as
well as cPickleCache.c. The latter wasn't seeing the corruption at all,
while the former was.

If this seems like a good idea I'm happy to make the change.
