I wonder why a "base" attribute is even restored, then? If there is no
care to restore the shared views, then views could simply be serialized

That's true in general. I wonder if it's possible to restore shared
arrays if (by virtue of "base" attribute) we know that the ndarray
shares the memory of another ndarray.
