I've written a few simple cython routines for assisting in creating
byte-aligned numpy arrays. The point being for the arrays to work with
SSE/AVX code.

The change recently has been to add a check on the CPU as to what flags
are

Right, my intuition is that it's like order=C -- if you make a new
array by, say, indexing, then it may or may not have order=C, no

Finally, I think there is significant value in auto-aligning the

based on an appropriate inspection of the cpu capabilities (or
alternatively, a function that reports back the appropriate SIMD
alignment). Again, this
