+ * NS7
+ *
+ * NOTE: This named instance is used to reproduce a scenario which involves a
+ * number of functions getting called in a very specific order which results in
+ * an infinite loop while iterating over NSEC3 red-black tree.  Ensuring this
+ * happens requires carefully setting the number of signing keys, NSEC3
+ * parameters (number of iterations and salt value), zone data and named
+ * configuration.  Changing any of these and/or influencing this instance's
+ * behavior (e.g. by sending extra queries to it) might render this test moot
+ * as it will no longer be able to reproduce the exact scenario it attempts to.
+ *
+ * Given the above, please do not use this instance for any other test than the
+ * one it was meant for.
