+ * 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.
