--- Comment #1 from David Binderman <dcb314 at hotmail dot com> ---
Reduced C code seems to be:

struct qlist_head {
  struct qlist_head *next
} qlist_add(struct qlist_head *new, struct qlist_head *head) {
  struct qlist_head *prev = head;
  new->next = head->next;
  prev->next = new;
}
struct {
  struct qlist_head queue_link
} free_list, prealloc[];
dbpf_open_cache_initialize() {
  int i = 0;
  for (; i < 64; i++)
    qlist_add(&prealloc[i], &free_list);
}
