           Summary: Use purgeable memory to keep more dead resources in
                    cache
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Platform
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: psolanki at apple.com


When we have purgeable memory available, we should be able to hold on to more objects that the dead size limit of the WebCore cache. Since the data is kept in purgeable pages, we can keep the CachedResource objects around until the kernel decides to reclaim the pages. At which point we can delete the cached resources.
