I vaguely remember that there was a sudden realization that the above mean
criterion was necessary but not sufficient for optimizing expected utility
in a zero-info environment.
I also remembered that you made excellent progress on the small population
case, and (prematurely?) gave you credit for an asymptotic solution in the
large population case :-)
