	The above does not really help.  nsdispatch() will be given specific
	address family from gethostbyname2() and obeys that.

	I'm trying to address the issue, by having _dns_gethaddr() variant
	for use from getaddrinfo().  I think we don't need to impose
	nsdispatch() and nsswitch.conf, thanks to very generic code in
	nsdispatch().  I'll try to commit it sooner.
