no_exists (Fam::Connection)

    /*
     * Gamin-specific extension for FAM to not propagate Exists events on
     * directory monitoring startup. This speeds up watching large
     * directories but can introduce a mismatch between the FAM view of the
     * directory and the program own view.
     *
     * Has no effect if FAMNoExists is not available.
     *
     * Raises a Fam::Error exception if an error is encountered.
     *
     * Examples:
     *   fam.no_exists
     *
