// Currently does not work on OS/2. With -xs, main() will register
// an exception handler that calls the destructor. When exit() is
// called, eventually the runtime calls DosExit. This will trigger
// XCPT_PROCESS_TERMINATE and the destructor will be run. Note that
// at that point the runtime has been shut down.
