  * milestone:  1.5.1 => Unscheduled


Comment:

 This is because the strides are being created differently from normal:

 {{{
 In [14]: a = np.ones(10)

 In [15]: b = a[None, :]

 In [16]: c = a.reshape(1,10)

 In [17]: b.flags
 Out[17]:   C_CONTIGUOUS : False
   F_CONTIGUOUS : False
   OWNDATA : False
   WRITEABLE : True
   ALIGNED : True
   UPDATEIFCOPY : False

 In [18]: c.flags
 Out[18]:   C_CONTIGUOUS : True
   F_CONTIGUOUS : False
   OWNDATA : False
   WRITEABLE : True
   ALIGNED : True
   UPDATEIFCOPY : False

 In [19]: b.strides
 Out[19]: (0, 8)

 In [20]: c.strides
 Out[20]: (80, 8)
 }}}
