Three things I have found that solve the stuttering from premature CPU
scaling on Android:

  * Don't use nesting. Having a single server architecture seems to keep it 
smooth.
  * Don't use double buffering (bug 1240909). Staying busy pre-rendering that 
third buffer keeps clocks higher and smoother.
  * Just wastefully spin a CPU core. Annoyingly, wasting power makes graphics 
visibly smoother.

Hopefully we can find more options.
