connect() does issue an immediate failure, though. If we
soconnect();soconnect(NULL); before the sosendmsg(), we get an
ENETUNREACH right away. Or if that's too much overhead we could just
check every N sends, or only during certain conditions or something
(e.g. during AFS shutdown).

Or we could look at the interface list or route list a la NetIfPoller()
and try to determine outselves how available the net is during shutdown,
but ew. Probably not worth the effort.
