STR:
1) Open http://planet.mozilla.org/, let it load
2) Press Home/End to scroll to the start/bottom of the page

Without APZ it's considerably smoother, but still far from perfect.

I'm not sure if we want to block APZ on this.

I'm leaning towards no, since routing keyboard input through APZ (the correct long-term solution) is nontrivial. If we really want to do a shorter-term fix we can make the home/end trigger smooth scrolling in APZ which should make it smooth. (I'm not entirely sure what it does now, but I assume it uses the layout's "AsyncScroll" code path which isn't really so async).

Maybe bug 1198966 could help here, but I'm not sure.
