It's worth mentioning that there was some discussion of adding an
allocator for aligned arrays. It got sidetracked into a discussion of
SSE support for numpy, but there are all sorts of reasons to want
aligned arrays in numpy, as this post demonstrates. Seeing as it's
just a few lines worth of pure python, is anyone interested in writing
an aligned_empty() for numpy?
