Ah ha. I thought about this and knew it was a high order, low order problem
but couldn't figure out the specifics. Now it makes sense.
Congrats to Andrew and Tom for figuring it out.

I would like to congratulate Andrew Bennett for correctly
puzzle. Below is his complete solution:

Note that this is a very deceptive prblem. When random data
is taken which
has a narrow distribution, it appears to be just fine. That
is because the
data is random and it does not care that the bytes are mixed
up. It still
gives a nice plot. It is only when the total spread of the
exceeds 256 that funny things start to happen. First there
are "side lobes"
spaced by 256 counts. For a broad enough distribution, the
shape with 256 counts between steps occurs. This is
devious, and leads one
to search for temperature effects - the problem first
appeard when I raised
the temperature to study the dark current.
