+Query Handle Lifetime
+---------------------

+Each callback provides an opaque anonymous information handle which
+can usually be further queried to find out information about a

+valid during the lifetime of the callback so it is important that any
+information that is needed is extracted during the callback and saved
+by the plugin.
