           Summary: LayerAnimation is not thread safe, which makes
                    dereferencing an expensive operation
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit BlackBerry
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: edbaker at rim.com

Before dereferencing LayerAnimation from the main WebKit thread the compositing thread needs to dereference first. This requires dispatching from the main WebKit thread onto the compositing thread which is an expensive operation. Making LayerAnimation thread safe would make this unnecessary and improve performance.
