With no signals and without c-ares, libcurl can't abort the resolve at the
desired time-out so you need to wait until the regular name resolve function

I've never seen anyone experience c-ares builds to not deal with timeouts
properly before. Are you using the latest libcurl and c-ares? If so, can you
provide us with the source for an app that repeats this problem?
