 Though the call to `dns.lookup()` will be asynchronous from JavaScript's
 perspective, it is implemented as a synchronous call to getaddrinfo(3) that runs
 on libuv's threadpool. This can have surprising negative performance
 implications for some applications, see the [`UV_THREADPOOL_SIZE`][]
 documentation for more information.
