It seems that lists are used as FIFO structures by appending, fetching & deleting last, all of which are O(n). ISTM it would be better to use the head of the list by inserting, getting and deleting first, which are O(1).I think you're referring to linked lists, but pglists are now arrays,
Ok… I forgot about this change, so my point is void, you took the right one.
