Can not disable johnny.cache if tasks have enable call

[ghost]

I have following statement at the beginning of my periodic celery task file:
from johnny.cache import enable
enable()

However, even I remove all johnny cache related settings (middleware, backend definitions etc), johnny cache was still enabled for entire project as you can guess. To disable entirely, I had to remove all enable statements.

I think proper solution would make enable() not work when JOHNNY_CACHE set to False in backend definitions (which actually don't benefit). I thought I have disable johnny cache when I did this but it was still there when I observed what was happening in memcached (can be seen using memcached -vv).
