Thanks Quincey. I do see where iOS will terminate the application
(SIGKILL) rather than calling applicationWillTerminate (the two
paragraphs under "Responding to Application Termination" coupled with
foreground/background/suspend state).
It sure would be nice if we could count on applicationWillTerminate
all the time. A SIGKILL without applicationWillTerminate seems kind of
rude :(
