I can't even load the page on my laptop. :(

If I could, I'd try to understand what textareas are so slow. Only think I can think of is that we load the old review page in an iframe that contains the full diff as text in the textarea. I could imagine that being slow. It's silly through really. We don't need to load the diff in that iframe at all anymore. Noone uses the old review page anymore.

We should fix the inefficiency on the C++ side first of course, but after that, we should just change the review page to not be dumb.
