Doc Text:	Cause: images younger than the threshold are not added to the dependency graph. Consequence: a blob which is used by a young image and by a prunable image is deleted because it has no references in the graph. Fix: add young images to the graph and mark them as non-prunable. Result: the blob has references and is not deleted.	Story Points:	---
