           Summary: Keep dead resources in memory cache in purgable memory.

          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading

OS X 10.5 has kernel facility for purgable memory that allows marking memory
area as less important. Under memory pressure system can steal pages that have
been marked purgable for better uses. We should use this mechanism for dead
resources in WebCore memory cache.
