           Summary: 6 objects and ~200MB leaked after opening then closing
                    tab
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
               URL: http://sailor月.com/dvds/
        OS/Version: Mac OS X 10.4
            Status: NEW
          Keywords: NeedsRadar
          Severity: Major
          Priority: P1
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bdash at webkit.org


Steps to reproduce:
1. Start a clean copy of Safari.
2. Enable "Always check for world leaks" in the debug menu.
3. Check the memory use of Safari via 'ps', 'top', or Activity Monitor.  It
should be around the 32MB mark.
3. Load the URL <http://sailor月.com/dvds/>.
4. Wait several minutes for the page to load.
5. Check the memory use of Safari again.  It will be around the 250MB mark.
5. Hit command-W to close the window.
6. Check the memory use again.  Note that it is *still* around the 250MB mark.

Some time after step 5. a dialog appears stating that 3 WebDataSource objects
and 3 WebHTMLRepresentation objects have been leaked.

Expected results:
No leaks.   I would also expect the memory footprint to shrink dramatically
after step 5 to bring it close to the original memory footprint.
