Caching asynchronous DNS resolver built on top of GNU ADNS http://www.chiark.greenend.org.uk/~ian/adns/.

Resolves several IP addresses for one host (if available) in round-robin fashion.
Limits number of parallel requests (so DNS resolving continues to work even under heavy load).
Errors are cached too (for one minute).
Handles CNAMEs (hsdns returns error for them).

This cache is tested in a long running web-crawler (used in http://bazqux.com) so it should be safe to use it in real world applications.
