+/*
+ * The time has come to get some order into this mess.
+ *
+ * From now on the following terminology is used:
+ *
+ *    alloc_		smalloc() the object. Increase _cnt.
+ *    free_		sfree() the object. Decrease _cnt.
+ *    clear_		free_() any objects contained in the object,
+ *			but not the object itself.
+ *     copy_		smalloc() a new object and also smalloc()
+ *			any objects contained in it.
