iPhone Application failing to come back from sigkill

I have no idea if this is intended be开发者_JAVA技巧haviour, but whenever the application exits (say, the user is double-clicking the home button and pressing on the red dash on the icon) I get the dreaded SIGKILL.

Now, when I try to launch the app again all I get is the old screen state and a frozen (I presume ?) program.

It could be because of clunky memory management, but NSZombieEnabled doesn't seem to agree.

Any thoughts ?

OK. Figured out what is happening:

Apps aren't "supposed" to be closed using the minus button. Instead what we do is save state during will enter background calls, state from which we can resume the application later on.

The debugger definitely doesn't like having your app being closed and kinda hangs the OS. To test close/resume/notification features, detach the debugger first.
