-1. It's difficult to use, and I question that there is any
benefit. I believe readv is there primarily for symmetry with
writev and hasn't any sensible uses on its own. writev is
there so you can add additional headers/trailers around data
blocks you received from higher layers. I even doubt that
exposing writev in Python would make a measurable performance
difference.
