I added this to the test code but it failed as:

Server: Created.
Server: Binded.
Server: Listened.
Client: Created.
Client: Connected.
Client: Written.
accept: Software caused connection abort

Of course, setsockopt() was added also before connect().

So, I moved the setsockopt() from just before accept()
to just before listen(), then it  succeeded.

Server: Created.
Server: Binded.
Server: Listened.
Client: Created.
Client: Connected.
Client: Written.
Server: Accepted.
10: 1234567890
Server: Read.

Does this affect to listen() as well?
