If I place a delay before each call of Roll, I get more
different values, confirming this time/speed dependence
of resetting the generator.

OTOH, the Size parameter is fixed at 6, so subtype Die_Size and
the generator could be placed outside Roll. Anyway, another
nest will give suitable life times to the objects involved.
