+ *
+ * Purpose: This test creates a file and a bunch of objects in the
+ * file and then calls MPI_Finalize without closing anything. The
+ * library should exercise the attribute callback destroy attached to
+ * MPI_COMM_SELF and terminate the HDF5 library closing all open
+ * objects. The t_prestart test will read back the file and make sure
+ * all created objects are there.
