I would rather call it ares_reload() or something...

I could see a use for some kind of timeout option that makes c-ares
automatically reload the data after some kind of timeout or similar.

But really, discussions and patches about possible c-ares improvements and
features should be taken to the c-ares mailing list instead of here. Believe
it or not, but c-ares is used by several other softwares than libcurl and
others may have different ideas and suggestions on this topic!
