(fd int)

//
// NewSocket takes ownership of fd.
func NewSocket(fd int) (*Socket, error) {
	// fd must be non-blocking for non-blocking unix.Accept in
	// ServerSocket.Accept.
	if err := unix.SetNonblock(fd, true); err != nil {
		return nil, err
	}

	efd, err := eventfd.Create()
	if err != nil {
		return nil, err
	}

	return &Socket{
		fd:  atomicbitops.FromInt32(int32(fd)),
		efd: efd,
	}, nil
}

// finish completes use of s.fd by evicting any waiters, closing the gate, and
// closing the event FD.
