           Summary: CachedResourceLoader is not deleted when page change
                    or close
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Major

         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: thomas.kim at lge.com


When a page is changed or closed, webkit doesn't release resources of current page.
It's very important thing on the device which has low memory.
I investigated of that. I found something.
Before merging http://trac.webkit.org/changeset/130817, The life cycle of CachedResourceLoader was with Document.
At this time, CachedResourceLoader was deleted when a page is changed or close.
After that, life cyccle was changed DocumentLoader for mainResources.
And CachedResourceLoader changed from OwnPtr to RefPtr on Document.
I think there are some memory leaks.
Please confirm.
