Might be worth looking at asio again, then.  I don't have free coding
cycles any time soon, though.

I've seen a lot of async network libraries do this - it's because
getaddrinfo is synchronous, so if you want to integrate it into a
reactor-type async main loop, you have to muck about with threads,
which is no fun.  Of course, writing your own DNS client is also no
fun, but I guess it's less bad from the perspective of the network
library author?

Linux has getaddrinfo_a, but that's not universal and suffers from
this bizarre notion that signals are a sensible IPC mechanism.
