It seems to be a natural idea to save Web application state from an unload event handler. But is it guaranteed that client-side database API is still functional at this point? And if it is - can one queue up more statements and/or transactions from statement callbacks?
There needs to be some limits put on this, as otherwise a script could continue to use resources indefinitely after a browser window is closed. But I do not see where it is specified, explicitly or implicitly.
