Details:

Do not call std::exit() in MApplicationPrivate::stdExit(int status)
because then all stack objects are still existing (e.g. QApplication),
but global static objects are cleaned up, leading to a lot of
side-effects.  Call qApp->quit() instead which will exit the event
loop and terminate the application cleanly.
