True, the category of close conditions around 'force close' for various things (like protocol errors, protocol violations, exceptions in the user websocket object, memory, networking, idleness, etc) will close the connection, usually with a blind send of a close frame, and then terminate of the connection. We can't rely on a proper handshake in many of these situations so it can't really wait on the close from the other side. But we still have an obligation to let the user websocket object know that the connection was closed.
