+/* This is a test of the special shutdown that occurs
+   when all threads, including the main one, call
+   pthread_exit(). It demonstrates that atexit
+   handlers are properly called, and that the
+   output is properly flushed even when stdout is
+   redirected to a file, and therefore fully buffered. */
