Notes: Notes:
1. The go.net io.Reader and io.Writer operate across WebSocket frame boundaries. 1. Chrome's [new WebSocket implementation](http://www.ietf.org/mail-archive/web/hybi/current/msg10503.html) fragments large messages.
Read returns when the input buffer is full or a frame boundary is
encountered, Each call to Write sends a single frame message. The Gorilla
io.Reader and io.WriteCloser operate on a single WebSocket message.
2. The application can get the type of a received data message by implementing 2. The application can get the type of a received data message by implementing
