 Physics and Maze use a lot of cpu (50% aprox) without doing anything.
 The log show a continue stream of:

 ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred.

 The activities don't use sound at all.

 Just to compare, in xo-1 use 39% cpu, and don't show the error msg, and in
 xo-1.5 use 20% cpu.

 Using the activity Maze on xo-4 for a while, I saw random crashes. (The
 easier way to trigger it was rotate the screen a few times, I am not sure
 if is related or not)
