I suspect NetBSD may be the first and only to return ENOBUFS for recv()
on ordinary UDP sockets, and that this has broken BIND, which is
treating ENOBUFS on UDP recv() as an unrecoverable error; see PR misc/53421
and http://mail-index.netbsd.org/tech-kern/2018/08/07/msg023815.html .

If there actually existed another OS that exhibited this behavior,
then surely BIND would have exposed the issue long ago, and either
BIND or the OS in case would have been fixed.

Please restore the old behavior, at least for UDP sockets.
