I stand corrected.

I still would really like people to pound dnsmasq flat with
namebench or other dns stress tests (anyone know of any? dig in a loop
would also help), using a native ipv6 dns server upstream. It used to
take days to trigger the bug. It may only happen on networks that have
issues with edns0.

Well, it was a more elegant solution that dnsmasq ultimately came up
with than what was in cerowrt, and I figure that single character fix
is a single bug report to openwrt and patch away... if someone else
not getting on a plane makes it.
