If I've understood your question correctly the answer is that sockets
are set to non-blocking mode when they are created so all operations are
non-blocking. Blocking operations are simulated by not returning to the
caller until the operation has completed. The reason for this is that
it allows a thread to be interrupted or killed from within the run-time
system.
