           Summary: Lazily allocate the SharedVideoFrameWriter in
                    RemoteDisplayListRecorderProxy
           Product: WebKit
           Version: Safari 16
          Hardware: Unspecified
                OS: Unspecified

         Component: WebKit Process Model
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: simon.fraser at apple.com

Every RemoteImageBufferProxy gets a SharedVideoFrameWriter, but only very few use it, and it has creation/destruction cost because it owns an IPC::Semaphore.
