1) Searching servers in order is IMHO not as problematic as the author
of dnsmasq suggests. If an udp packet gets lost, a name does not get
resolved, because you may switch to the following nameserver. Yet, it is
sufficient to retry the operation to have a good chance of success.
Which is exactly the behavior that you get with the libc resolv.

2) An alternative would be not to search sequentially, but to keep
asking the other nameservers, in case the first that answers fails
resolution.
