9815 | // operation to finish, and that would be the client's own fault). | |
9816 | // | |
9817 | // - If we have more than one client, each client will observe | |
9818 | // whatever is the state at the moment of the commit. So, if we | |
9819 | // have two clients, one issuing an unlink and another issuing a | |
9820 | // link, and if the link happens while the unlink is still on the | |
9821 | // pending state, from the link's point-of-view this is a no-op. | |
9822 | // If different clients are issuing conflicting operations and | |
9823 | // they care about that, then the clients should make sure they | |
9824 | // enforce some kind of concurrency mechanism -- from our | |
