Comment(by riccardo):

 patch v3 to util.py uses "if key in cache: ... else: ...". I still prefer
 v2 as we search the key only once.

 v3 still uses os.environ['LANG'] as I couldn't find any user of
 setlocale(..) in sugar and, gettext.py also uses environment variables to
 build the list of languages in its gettext.find(..) method.

 I tested the patch in english, french and arabic and it seemed to work ok.

 About using an LRU:
 How to find an heuristic to set the queue size ?
