[issue18473] some objects pickled by Python 3.x are not unpicklable in Python 2.x because of incorrect REVERSE_IMPORT_MAPPING

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I think that both UserDict.UserDict and UserDict.IterableUserDict should be mapped to collections.UserDict. And reverse mapping should map collections.UserDict to UserDict.IterableUserDict.

There are similar issues with other "multiple to single" mappings (e.g. to "io", "dbm", "http.server").
