If a component emit Ecore_Event and they aren't processed before the
call it call ecore_shutdown, there is no way to prevent this event
from being triggered after the component at shutdown itself. Which
may well lead to a use after free case. As we don't know which event
are pending and we also are not shuting down ecore completely as they
are still other component using it, we can only flush all pending event
right away.
