I remember the mid-90s when we were writing MUD servers and clients. You'd start the client, go "/world ZebraMUCK" and then the TUI would hang while the DNS name resolved.
So then we figured out asynchronous DNS (this was in the days when you linked with "-lresolv" on SunOS) and it was like a breath of fresh air! You could go "/world ZebraMUCK", control was returned to the keyboard, and even if it took 120 seconds to resolve zebramuck.nozebra.example.com, you could go about your business, like in another world, or issue some other client commands.
And client developers learned a little about select(3).
