A cache would be a band-aid -- it still will have to do these lookups
occasionally, and the user experience in Gnus suffers.

As it stands, librgravatar shouldn't be the default gravatar provider.

But, yes, Emacs should have asynchronous DNS support, and adding that
probably isn't too difficult, I'd have thought?
