I actually still have this question but now have another, related one that I'm
puzzling over. What does it mean when my key cache size is 0 but I've got a
successful hit rate?  For example:

        Key cache capacity: 100
	Key cache size: 0
	Key cache hit rate: 0.75


I'm sorry for the barrage of questions!
If anyone knows the answer to this, thank you in advance.
