-// WebSocketDeflateStream is a WebSocketStream subclass.
-// WebSocketDeflateStream is for permessage-deflate WebSocket extension[1].
-//
-// WebSocketDeflateStream::ReadFrames and WriteFrames may change frame
-// boundary. In particular, if a control frame is placed in the middle of
-// data message frames, the control frame can overtake data frames.
-// Say there are frames df1, df2 and cf, df1 and df2 are frames of a
-// data message and cf is a control message frame. cf may arrive first and
-// data frames may follow cf.
-// Note that message boundary will be preserved, i.e. if the last frame of
-// a message m1 is read / written before the last frame of a message m2,
-// WebSocketDeflateStream will respect the order.
