We have a project that relies on sending large amounts of data via WebSockets and Safari is our primary supported browser. A recent update has broken Safari's WebSocket implementation and from what we can tell there's no immediate workaround.

Our first attempt was to write code check the `bufferedAmount` property to manage how much data is sent to Safari but it is always reporting 0 as of this recent release. I'm hoping this will catch someone in on the Webkit team or that someone on HN will have an alternative idea for a workaround in the meantime.
