               vector[ 1 ].iov_base = NULL;

"Don't do that" :-)

I'll doubt I will bother to fix it (it's not %100 trivial to fix and
it will put a cost into a hot path). Even if I did, you're going to
need to fix Zeus not to do writev's with empty iovec's like this so
that you get the PSH's in current kernels.
