http://src.chromium.org/viewvc/chrome/trunk/src/net/dns/dns_transaction.h?view=markup

It's OOP-based, and far simpler because it doesn't (yet) try to
provide all the functionality that is specified in the getdns() API.
As you can see, you create a DNS transaction object. You construct it
with the input parameters, and then call the asynchronous Start()
member function. It can synchronously return an error or
asynchronously complete.

This API is clearly not suitable for y'all since it's C++ based, but
we don't foresee issues writing a C++ wrapper around a getdns() API
like the current proposal, if we so desired.

Btw, I don't really want to make the Chromium API a focus of this
discussion. I just wanted to offer some clarifying information.
