            Bug ID: 251892
           Summary: CachedFont objects gets created for every 'src'
                    attribute in @font-face rules, even if they're never
                    loaded.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: Text

The combination of CachedFont, CachedFontLoadRequest and CSSFontFaceSource add up to a significant chunk of memory, which is largely unneeded until we actually load the fonts.
