Maybe call this something else than "cleanup" since it actually invokes the completion handler.

It would be slightly nicer if this was a struct with named fields though I suppose that would make using it as hash key more complicated.

How strongly do you feel about this? :) As you said, I would need to provide HashTraits if I did this. Also, the code should really not need to access actual pair values. The only code that does currently is the Cache Statistics code which is not production code.

Not strongly at all.
