Thank you for your answer, Alexander! I like your patch and it looks similar to my first version of it before I came up to the possible segment size problem.
>Also, I don't think we should change segment size to uint32 as it's already defined as int in awfully a lot of places I agree that changing segment size type is probably out of this thread and problem scope, but suppose it would be great if someone could tell me the story behind signed segment size as I see it is better unsigned.
