did you try to short-circuit the code to delete the cached value and refill 
it with the new copy of the dict to see if it's a culprit of your code or 
of the cache ?
Mind that cache.ram has some subtle differences because it just stores a 
pointer to the object, not the copy of the object like all other backends
