@movq yeah.. i rewrote it a few times because i thought there was something breaking.. but was mistaken
though now i am seeing a weird cache corruption.. that seems to come and go.

I have found the issue with this very subtle bug.. the cache was returning a slice that would be mutated. The mutation involved appending an item and then sorting. because the returned slice is just a pointer+length the sort would modify the same memory. 



          CACHE         Returned slice          
original: [A B C D]     [A B C D]
add:      [A B C D] E   [A B C D E]
sort:     [E A B C] D   [A B C D E]
