Consider the std lib only.
Is a net.Listener or a net.Conn closed when a non-nil error is returned by Accept() / Read() / Write() ? Except for situations where the error is os.ErrDeadlineExceedes.

You could look through the stdlib code to make sure

You'd have to download the go toolchain anyway if you want to do anything with go. So if you habe the toolchain for building Go code, you have the standard library on your machine as well.
