Yes this is very dangerous. There is a good chance that if the user hits
home, and later returns to your app, the process will have been killed and
all static data in it lost. This is very unlikely to happen when just
switching from one app to another (the process in that case stays in the
foreground bucket), but still I am not going to make any guarantees.
