           Summary: NamedNodeMaps created from Atomic Tokens use 4 MB on
                    Membuster
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: slewis at apple.com


The AtomicHTMLToken function reserved space for ten tokens in the attribute map which was rarely filled.  Rework the function to reserve space for the number of attributes in the list.  Seems slightly faster on the parser benchmarks.  Saves 1.5 MB on Membuster.
