Content
It doesn't help that neither PEP 3118 nor the Py_buffer docs mention the "obj" member of the Py_buffer struct that refers back to the original object providing the buffer - that's fairly fundamental to understanding how PyBuffer_Release and PyMemoryView_FromBuffer can work even in theory. (Given that, an additional _PyManagedBuffer object shouldn't be necessary - MemoryView just needs to call ReleaseBuffer and GetBuffer at the appropriate times)
