Would that I had more upvotes for this.

The actual cutting edge of event-driven server architecture[1] looks something like this:

    server = do {
      sys_call_1;
      fork client;
      server;
    }

    client = do {
      sys_call_2;
    }

(And even then it has marginal benefits in terms of throughput and latency compared to threaded implementations.)
