title: Close Delphi dialog after [x] seconds
body: <p>Is it possible to get Delphi to close a ShowMessage or MessageDlg Dialog after a certain length of time?</p>
  
  <p>I want to show a message to the user when the application is shut down, but do not want to stop the application from shutting down for more than 10 seconds or so.</p>
  
  <p>Can I get the default dialog to close after a defined time, or will I need to write my own form?</p>
