Sets the non-blocking mode of the native acceptor implementation.
void native_non_blocking( bool mode);
This function is used to modify the non-blocking mode of the underlying native acceptor. It has no effect on the behaviour of the acceptor object's synchronous operations.
true, the underlying
acceptor is put into non-blocking mode and direct system calls
