           Summary: Allow JSObject to fully utilize cell's capacity for
                    inline storage.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


Currently JSObject is both directly instantiated for regular JS objects, and derived to implement subtypes.  A consequence of this is that we need to ensure that sufficient space from the cell is left unused and available for any data members that will be introduced by subclasses of JSObject.  By restructuring the internal storage array out of JSObject we can increase the size in the internal storage for regular objects.
