Question about lookupByOff in delEntryPtr

[pingworld]

Thanks for your repo.

I feel confused when I read the del func of segment. Why there is another lookupByOff in delEntryPtr while you have been got the idx by lookup. I have checked the codes carefully, but I still can't find out they can return the different values.

I want to know If there is other consideration for checking it again to assure safty.

Any reply would be appreciated.

I read the code again and find out that the second lookup can be avoided.
I will push a commit soon.
Good catch, thank you!
