For rocksdb, maybe it's here? Which (I think) goes here?

The github issue said:

Due to the lack of performance tuning of RocksDB, the current ahnode api performance is seriously insufficient.

I still don't understand why it works the way it does, though. Maybe an off by one error in this loop?

And/Or maybe this should be > instead of >= ?

I'd need to step through it line by line to understand, but I'm not that curious. ;-)
