------------------------------------------+---------------------------------
 This problem was detected in olpc xo-1.0 using Dextrose image from Uruguay
 (dxo-uy-1.0).

 After executing in python:
 {{{
 import pygame
 pygame.init()
 }}}
 the proccess pulseaudio shows 10% cpu usage.

 Changing the SDL audio driver is a workaround:
 {{{
 import os
 os.environ['SDL_AUDIODRIVER'] = 'alsa'

 import pygame
 pygame.init()
 }}}
