 * which should only be called after some time of icactivity, which is typically
 * the case of 'item-change' handlers.
 *
 * The structure is supposed to be initialized at construction time with
 * @timeout in milliseconds, @handler and @user_data input parameters.
 * The private data should be set to %NULL.
 *
 * Such a structure must be allocated for each managed event.
 *
 * When an event is detected, the na_timeout_event() function must be called
 * with this structure. The function makes sure that the @handler callback
 * will be triggered as soon as no event will be recorded after @timeout
 * milliseconds of icactivity.
