Don't worry about that failure on Travis... It happens randomly on at
the moment and its unrelated to anything you are doing.
I am not sure though you can change behavior like that since you also
change the default behavior of the `.copy()` method and someone might
rely on that? Maybe making it specific to the copy model would make it
unlikely that anyone relies on the default, it would seem sensible that
copy.copy(array) does basically the same as np.copy(array) and not as
the method .copy, though ideally maybe the differences could be removed
in the long run I guess.
