How delete and deleteLater works with regards to signals and slots in Qt?

There is an object of class QNetworkReply. There is a slot (in some other object) connected to its finished() signal. Signals are synchronous (the default ones). There is only one thread.

At some moment of time I want to get rid of both of the objects. No more signals or anything from them. I want them gone. Well, I thought, I'll use

delete obj1; delete obj2;

But can I really? The specs for ~QObject say:

Deleting a QObject while pending events are waiting to be delivered can cause a crash.

What are the 'pending events'? Could that mean that while I'm calling my delete, there are already some 'pending events' to be delivered and that they may cause a crash and I cannot really check if there are any?

So let's say I call:

obj1->deleteLater(); obj2->deleteLater();

To be safe.

But, am I really safe? The deleteLater adds an event that will be handled in the main loop when control gets there. Can there be some pending events (signals) for obj1 or obj2 already there, waiting to be handled in the main loop before deleteLater will be handled? That would be very unfortunate. I don't want to write code checking for 'somewhat deleted' status and ignoring the incoming signal in all of my slots.
