I use the split-thread view, I haven't had long page loads so 
maybe I've miss understood what he means by a hiccup. But I have 
seen it take time to retrieve a message and display it to me. I 
would expect a page could be considered "loading" if it is still 
waiting on fetching the post from the NG.
