Responsible-Changed-Why: 
Robert, can you please look into this?  POSIX says that EINVAL
may be returned if "the sum of the iov_len values overflows an
ssize_t".  I see a similar code in FreeBSD:

        for (i = 0; i < mp->msg_iovlen; i++, iov++) {
                if ((auio.uio_resid += iov->iov_len) < 0) {
                        error = EINVAL;
                        goto bad;
                }
        }

except the type of uio_resid in FreeBSD is "int".  (On NetBSD,
it's size_t.)
