new HsDNS version available

[Peter Simons]

In case anyone is using my Haskell bindings to the GNU ADNS
library, you might be interested to know that a new version
of the package is available here:

  http://cryp.to/hsdns/

There have been quite a few significant improvements
recently, most of which concern exception-safety,
efficiency, and documentation. PollResolver.hs, in
particular, has been cleaned up a lot.
