Comment(by m-paradox):

 I think this is working as expected, because Fake never makes a view of
 the array.
 Observe:

 {{{
 >>> import numpy as np
 >>> class Fake(object):
 ...     def __init__(self, data):
 ...         self._data = data
 ...     def __array__(self):
 ...         return self._data
 ...
 >>> x = np.array([1,2,3])
 >>> print np.asarray(Fake(x)).flags.owndata
 True
 >>> np.asarray(Fake(x)) is x
 True
 }}}
