Thierry Crozat 63627dc26d IOS7: Save state as a background task when entering background
This is better than using an hardcoded delay for two main reasons.
The first one is that the application can terminate as soon as it
has finished saving the state, and the second one is that it will
still work if saving the state takes longer than the delay that
was hardcoded.
