            Bug ID: 186683
           Summary: DisplayRefreshMonitorMac should hold a weak pointer to
                    WebPage.
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: pvollan at apple.com

Instead of DisplayRefreshMonitorMac having a RefPtr to WebPage, it should have a weak pointer. Having a RefPtr could in theory create reference cycles. I have not seen any cases of this, but I think it would be better design to hold a weak pointer.
