This doesn't mean resolv.conf is never closed. It just means you've
already run into your open file limit when something tried to open
resolv.conf.
You didn't mention which version of Twisted you're using. Perhaps
you're running in to #970 (fixed in 10.0).
But if you just want to use a particular server, then maybe you want to
instantiate twisted.names.client.Resolver directly, rather than calling
createResolver.
