Applications can detect being shut down (via the onterminate handler) at
which point they do all the stuff that they would if the user shut them
down manually or if the system decided to close them (Android does
something like that).

What would happen in Tizen if applyUpdate() is not called? Is it implicitly
called as soon as the application is not running?

If so, is the only purpose, from the developer's point of view, of the
function to close the application if it's currently running? From that
perspective calling the function exit() doesn't seem so strange.

In other words, it's somewhat strange to have a function called
applyUpdate(), if the update is applied even when that function is not
called.

But I agree we need a function that has the behavior "force-close the
application if it is currently running, if that is platform convention once
an update has been downloaded".

It just seems a little bit strange to call that function apply update, but
I don't have a better suggestion.
