Both Qt and Lua provide functions which may not be appropriate depending on 
the situation. The os.exit Lua function is not appropriate here because it 
calls the libc exit function which doesn't unwind the stack. The cleanup of 
various C++ objects is not performed properly in this case. Use app:quit() 
instead. You may want to drop the os.exit function and other such lua 
functions to prevent their use if it's critical in your application.
