I understand. But I'm thinking in terms of, say, 80000 users with
UIDs numbered from 0 to 79999. So in my case, there's no intrinsic
problem beyond the fact that it's a helluva lot of users. It would
be different if I had 80000 users numbered from 1000000 to 1079999.
That's what I meant when I referred to the packing of the UID space.
