I guess, I was approaching the problem from the wrong side.
What I am really interested in are the implications of this
fact for the programmer. What I believe to have understood
so far is:

  You have no guarantee that a finalizer you registered
  will ever be run -- even if the program terminates
  normally.

Is that correct? Or did I misunderstand something?
