    file.TraceEvent += new TraceEventHandler(handler.TraceEventHandler); 

    EventTraceProcessLogs process = new EventTraceProcessLogs();
    process.AddTrace(file);

    EventTraceOperationObserver observer = new EventTraceOperationObserver();

    observer.Completed += new CompletedEventHandler(procHandler.CompletedHandler); 
    process.Process(observer);

    Console.WriteLine("Waiting 10 seconds...");

    Console.WriteLine("Waited too long, cancelling...");
