Numpy > np.may_share_memory() > may give you false positives

You can use np.may_share_memory() to check if two arrays share the
same memory block. Note however, that this uses heuristics and may give you false positives.

A return of True does not necessarily mean that the two arrays share any element. It just means that they might.
