I don't think I'd seen the logging stanza, but yes, logging to syslog is a bad thing, and logging queries to syslog is even worse.  Having had someone pick this out of an strace output is indeed awesome.

I think the simplest thing would just be to have an exclusion in the syslog config for named. I confess some general ignorance, so perhaps you know the directive for that?

To reduce the load on named in general, just turn off query logging in the named.conf, or, you can leave the stanza in and put a "querylog no;" in your options stanza so that it is not started when named starts (I'm not sure what version introduced the querylog option, so you may need to test this.
