+     * once per 2^39 new node initializations / identity creations. If you do

+     * with other nodes.</p>

+     * <p>We'd automate this process, but we don't think silently deleting
+     * private keys or changing our address without telling the calling code
+     * is good form. It violates the principle of least surprise.</p>

+     * <p>You can technically get away with not handling this, but we recommend
+     * doing so in a mature reliable application. Besides, handling this
+     * condition is a good way to make sure it never arises. It's like how
