           Summary: [Chromium][DRT] some PostDelayedTask() accesses
                    possibly dangling this pointer.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: morrita at google.com
                CC: fishd at chromium.org, tkent at chromium.org


In WebViewHost, there are several calls like: 
    webkit_support::PostDelayedTask(invokeFinishLastTextCheck, static_cast<void*>(this), 0);
But this is not safe when |this| object is deleted before the task callback is invoked.
