[translations] determining correct import

[Jakub Suchy]

Hi,
regarding to autolocale, i would like to ask if we have any option to
determine language was correctly imported or not.
Too many users on drupal.cz reports either their memory or time limit is
exceeded or no error is printed and import was unsucessful (= less than
100% was imported). We need some fallback or determine a way how to
speed up the process (cron?)
