QCoreApplication. quit() and exit() does not exit immediately

From documentation on QCoreApplication::exit():

Note that unlike the C library function of the same name, this function does return to the caller – it is event processing that stops.

for method QCoreApplication::quit()

Equivalent to calling QCoreApplication::exit(0).

Try this code

            qApp->quit(); // behavior same as qApp->exit()
            forever {
                qDebug("I'm not compiler, but i can spam too!");
            }

Need update documentation for exit() and quit() methods and append this example as main solution for correct exit:

    Q[Core]Application::quit()/exit();
    return;
    ... // here some code

Or may be change implementation and add two new methods: quitLater(), exitLater() like deleteLater().
