Your original sequence is correct. No one has been recommending swapping the order of 4 & 5.

You could try and terminate a context in a thread, but it will *block* until all sockets close and clean up. Unless you want this behavior, you should clean up sockets first.

In other words, an application may (intentionally) dispose of the context while one, or more, sockets are still "live". Is this true? If so, can anyone elaborate on when this is necessary?
