I was not trying to save state for orientation change, but for general application state preserving while getting into background in case OS decided to kill/restore application.
The ANR assumption is wrong. While OS makes all these activity calls on UI thread, there's no direct time limit applied; I tried explicit 10 seconds delay and OS does not kill my test application. BTW, UI does not appear frozen; I suppose UI thread is still per-process, so that when OS is switching application the delayed state save call does not matter. Now my assumption is that if during that state save process OS requires even more memory immediately - it just recycles the process, whatever state it was in. That means that any application could be killed this way; just those who spend more time within state save are more vulnerable statistically.
