We have all the information we need when deleteLater() is called, so there's no point in deferring it until the event is posted, which requires friended access into the QDeferredDeleteEvent's members. Moving the code focuses QCoreApplication::postEvent() on its primary task, posting of the event (adding to the event list, waking up the event dispatcher). It's also easier to reason about how the action of deleteLater on an object relates to the event loop and scope level when the information is resolved up front.
