Currently resolver caches positive DNS answers only.
Wrong names are not cached, so each worker reports about each wrong name.
This causes spam in logs, especially when we use nginx-upstream-dynamic-servers module.
Caching of negative DNS responses should solve that.

Is ngx_resolver worker-local, or shared between workers?
