Sounds like a fun exercise.  I do not think it breaks anything, and
because we have the list of objects to be placed in the resulting
pack fairly early in the process, this sequence would be possible:

    (1) enumerate the objects;
    (2) compute the resulting packname;
    (3) notice it is the same as an existing one;
    (4) add another dummy object and go back to (2);
    (5) do the heavy-lifting of delitify;
    (6) write out the resulting pack.

inside pack-objects.

I do not know if the loop between (2) and (4) is the only necessary
thing to completely avoid the race you are worrying about, though.
