Core Animation handles the threading aspects of this automatically.
The introduction should have been clear about it (if not, file a bug
with what was unclear)

I have gone over the CA docs ... a quick read.
I have an iPhone app that uses the accelerometer to move a puck
around the x,y plane. It filters out the effect of gravity per the
sample code.
I would like to animate two background layers, one rotating cw the
other ccw and use different CG blends based on the current location
of the puck.
Do I need to make the animation in a separate thread or does CA
handle that for me? I.e. I need responsiveness from the
accelerometer and the visual effect of the rotating backgrounds/
