           Summary: allocate numbers in half-size cells, for an 0.5%
                    SunSpider speedup
           Product: WebKit
           Version: 523.x+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mjs at apple.com


Numbers are already in a separate heap, and only need half the size of a normal
cell. Allocating them in half-size cells should be a perf win overall.
