deleteLater() events (DeferredDelete) are handled specially, to avoid 
something like:

	obj->deleteLater();
	obj->something();
	run a dialog
	obj->somethingElse(); // crash here

DeferredDelete events are only handled at the same loop nesting level that 
they were created in or less deep nesting. They are never handled by deeper 
nesting levels.
