I was just referring to how David was benchmarking the cost of
multiarray in isolation, which can indeed be done, and is useful for
understanding the cumulative effect.

Indeed for your case, it's the sum total of what import_array does
that ultimately matters, but it's still useful to be able to
understand these pieces in isolation.
