Is string storage really that big a portion of the browser's memory usage? I find it hard to believe that my browser is currently storing nearly a gigabyte of text right now I'm not saying that there wouldn't be performance overhead, but would it be significant? I would be surprised if it made a big difference. For legacy reasons, there probably isn't a point in changing it. But I'd be surprised if performance reasons turned out to be gating.
