One independent view of outside-block events emitted after opening.

Taking from one watch never drains another watch or the Connection's legacy event queue. The retained log is shared and bounded; this watch's dropped count reports only events this watch actually missed.

A watch retains the stream state. It can drain already-buffered events after its Connection is moved or destroyed; waits then wake as a closed stream.
