"Reading notes" gcd-network programming should not use GCD

One, the use of asynchronous APIs is highly recommended for network programming.

Two, for network programming can assert "thread is devil". If you use threads in network programming, you are likely to have a tendency to use threads with lots of problems. For example, each connection uses threads, and soon runs out of thread stack memory. Because the Cocoa Framework provides APIs for asynchronous network communication, it is not necessary to use threads in network programming, so be sure to use the APIs for asynchronous network traffic.
