Can you please try r227790 (one before r227791) to check whether this printf from
in_scrubprefix() existed before. It looks to me that this message is harmless, and
the real problem is sosend() returning EINVAL. That is probably also fallout from
r227791, but I suspect that digging into in_scrubprefix() is a wrong direction.
