The Delphi online help says that Release should be used to remove a form from memory. However, in many examples for modal forms I have seen this construct:

MyForm := TMyForm.Create(nil);
try
  MyForm.ShowModal;
finally
  MyForm.Free;
end;

Is Free a safe way to destroy a modal form? As I can see in the source for ShowModal, Application.HandleMessage will be called until the ModalResult is not 0. Is this the reason why Free can not interfere with pending windows messages?
