When scrolling up and down on Twitter on the HD8 with WR enabled, I saw a lot of checkerboarding. Profile seemed to indicate the content main thread was busy running JS. However we do have a mechanism to interrupt JS and force a repaint which is supposed to help here. We should investigate if that still works or if it's busted.

I guess I misremembered what this code does. It seems to be used only for the tab switcher; to force the new tab to paint to make tab switching seem more responsive. It doesn't get used if you're just scrolling around on a page. Bug 1279086 originally added it.
