BIND - disabling IPv6 lookups

Hello list,

I'm currently experiencing this very weird behaviour with BIND 9.8.7
running on 10-STABLE and, obviously, installed from ports.

I'm trying to prevent BIND from trying to resolve AAAA resource records.

To this effect, I've added :
named_flags="-4" to /etc/rc.conf, as the man page and several google
searches suggest [1]

After restarting BIND, I see it's come back alive with the correct startup
flag :
/usr/local/sbin/named -4 -u bind -c /usr/local/etc/namedb/named.con

However, I still see queries for AAAA records :
13:39:26.990819 IP > 195.158[snip].53: 43577+ [1au]
AAAA? (45)

Is that expected behaviour ?
And yes, is the actual FreeBSD box, not a client host trying
to resolve stuff.
