Review comment:
I dont see how this happens. Everything that needs to be deleted is
guaranteed to be in PathCleaner's deleteActions list by the time shutdown is
called. PathCleaner goes over everything in the list before exiting. See:

I didn't get your point with 1024 entries either. That is just the initial
