spec</a> for a mechanism for logging out users from all RPs of an OP. If you'll forgive me for my stupidity, one aspect of the spec wasn't clear to me: When the OP renders the HTML page with all the iframes, how does it know how long to wait before it can redirect
 to the post_logout_redirect_uri? Would it redirect the moment the page has loaded, treating the iframe requests as fire-and-forgets? Or would it wait until the iframe has loaded to try to detect whether the logout has been successful? Or is that sort of consideration
