There's the ndarray constructor, which lets you do some highly dodgy
things like create arrays whose rows overlap in memory. I would think
it would be possible to do this with that. You might also want to
think about allowing arrays to have their rows aligned (for example, a
100 by 100 array of float32s which wants 64-byte alignment for every
row).
