The existing internal section list is implemented as a singly-linked tail queue, and exhibits poor (O(n)) performance for some library functions (e.g. elf_getscn(), elf_strptr()). By replacing the queue with a resizable array, we can obtain O(1) access time and O(1) insertion time, since each section already keeps track of its own index.
