Not a bug... WebKit's impl holds all resources in memory for caches that are in use, so documents that are associated will still be able to access those resources even after makeObsolete has done its work. 

Chrome's impl doesn't hold everything in memory so when a group is made obsolete we can't delete the resource data from disk. Equating this delete function to making a group obsolete is close but not quite right.
