Remember the computer is a million times faster than the network. It sends
a bunch of packets and receives a bunch of packets, the time taken to
process a packet is tiny compared to the response time of a DNS server. It
can all be done at the same time on the same thread, the choice really
depends on how you like to interface to your network API.
