Implementation detail.

I don't think we have or want to have a policy of C-contiguous return 
values -- if you need C-contiguity, you'll need to ensure it by using 
`ascontiguousarray`.

Especially when we later on implement memory access pattern optimizations 
for ufuncs, such assumptions will break down even more often.
