// QStream is a wrapper of quic.Stream that handles Close() in a way that
// makes more sense to us. By default, quic.Stream's Close() only closes
// the write side of the stream, not the read side. And if there is unread
// data, the stream is not really considered closed until either the data
// is drained or CancelRead() is called.
