Hmm... some further local discussion has made me aware that us running "collectd" for monitoring BIND may be contributing to the problem; collectd fetches data each 10s by using the BIND- configured statistics-channel, thus BIND is processing a TCP connection to deliver the statistics data.
It's still somewhat surprising and disappointing that this should interfere this much with DNS query processing...
