### Alternative approaches

I prefer to avoid overhead from using threads for DNS lookup, so I dislike getaddrinfo_a || (getaddrinfo + pthread), too.

It would be ideal if we could try and evaluate both approaches. But my current impression is that using c-ares is the quickest and best compromise.

What about resolv.rb? I don't believe CPU/memory use in DNS lookup is a bottleneck for most users (network latency is); and prefer motivating improvements in Ruby VM + socket ext instead of linking against another C library.
