Given how quickly this surprised someone, it looks like it would be
helpful to have some single link we could give people to explain
what's going on here. Do we have such a thing? In a few minutes of
searching all I was able to find was

http://docs.scipy.org/doc/numpy/release.html#npy-relaxed-strides-checking
https://github.com/numpy/numpy/blob/master/doc/release/1.10.0-notes.rst#relaxed-stride-checking

which together kinda sorta hint at what's going on if you squint, but
not really? Maybe we should add a paragraph to the 1.10 release notes?
