Node defines "onread" property on the stream'sprototypeobject while it sets the value via streaminstanceobjects. This approach heavily depends on non-standardSetAccessor's semantics. The right fix would be to define "onread" property as a JavaScript accessor usingv8::ObjectTemplate::SetAccessorPro...
