If SDL is actually using a real timed sleep, it would help, but I don't 
think it does. This is often too inaccurate for games, so we may need to 
look at that ourselves. Because pygame is polling driven (instead of 
using async callbacks like GTK) it is unlikely that it will ever get as 
nice a battery life as GTK-based activities.
