long wait in BackKeyPress causes the app to be killed

[marcomura]

Hi devs,
today I noticed for the first time that if you wait too much inside a BackKeyPress event handler (easy if you open a MessageBox inside that) your app will be killed by the OS.
It happens only for apps signed... I tried with unsigneds in both debug and release configuration, in both device and emulator, and they aren't never killed.

I also noticed that signed apps are not killed in WP7... it seems to be a "WP8 thing".

As I said, I discovered this only today and I'd like to know if this is a new thing coming with GDR3 or if it's an older behavior.

Is there anyone still in GDR2 that can be test this?

Thanks in advance!

FYI: this is a bug in WP8 that exists since GDR1.

I suppose it kind of makes sense that the OS is killing the app if it is failing to respond on a back key press. It would seem as if the app really should be quitting by that point, and if it hasn't then the OS kills it.
