Die in case writing the index fails, so that the caller can notice (instead of, say, being impressed by how performant the writing is).
While at it, note that after opening a lock with `LOCK_DIE_ON_ERROR`, we do not need to worry about whether we succeeded. Also, we can move the `struct lock_file` into the function and drop the staticness.
