I'm not sure if unittest.mock code to import the module is reliable: see bpo-39551. It imports "multiprocessing", use getattr() to get multiprocessing.shared_memory. If getattr() fails with AttributeError, it tries to import "mulitprocessing.shared_memory", and then tries again the same getattr() on the previously imported "multiprocessing" module.

I'm curious if this change works around the issue:
