=> more than 16000 directories in it.

We have to:

• find and use a setting to get less directories in one single directory
• clear empty directories (recursively) when we delete cache

Idea : don't use ./symfony cc but instead move cache to cache.old, create cache, fix perms, and then delete cache.old.
