It looks to me like it would be a problem if you managed to get two ScriptedAnimationController instances to request animation frames. The second one would fail to register with the monitor.

I'll see if I can put together something that manages to do that (it may be impossible due to more high level mechanisms, not sure).

The reason I ran into this is not a specific bug, but development on a new feature for the BlackBerry port, perform accelerated compositing sync on a requestAnimationFrame instead of a 0-timeout timer. The idea is to service all the JS animations first, and then perform the AC sync last, to make sure their most recent animation changes become visible immediately.
