ZF-11171: Zend_Translate_Adapter_Gettext fopens and doesn't fclose
In _loadTranslationData, Zend_Translate_Adapter_Gettext fopens the translation file and never fcloses it.
This can result in PHP holding a lot of open file handles for files that, as far as I can tell, have already been fully processed. Handles for any invalid files encountered during a scan are also held.
In particular, it seems like there should be fclose calls before both "is not a gettext file" exception throws and before the function returns.
