Glasser is the man, as usual! He figured out that it is
triggered by having "Norton AutoProtect" running. I've filed a
bug with Apple, including everything necessary to reproduce.

Now, what should *we* do about it? Maybe:

  - Add a FAQ entry
  - Stop unlinking files we know don't exist
    We know whether the rename failed or not; only unlink if so.
    We should probably audit other del_on_pool_cleanup use, and,
    for that matter, all unlink calls.
