           Summary: Reduce memory use for static property maps
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


Static property tables are currently duplicated on first use from readonly memory into dirty memory in every process, and since the entries are large (48 bytes) and the tables can be unusually sparse (we use a custom hash table without a rehash) a lot of memory may be wasted.
