Go to https://js1k.com/2013-spring/demo/1390 Let the demo run. Maybe try clicking on the "reload" button within the demo UI. 8 times out of 10, the demo will start to lag quite a bit. At this stage, interactions with the browser UI become very sluggish - try hovering mouse over the toolbar icons, or clicking on the hamburger menu, or clicking the "+" icon to create a new tab.

Expected Result: No matter what the contents of the browser, the browser UI should never lag. Lag makes for poor user experience.
