On another note, I've just tried it with out any of the debugging
stuff compiled in and that did not make a difference. Now seeing if
hz makes a difference.

On a interesting note, I did find that with out invariants, the noise
on the +5V GPIO line is different. It takes awhile for longer for
each of the additional 3 sections to form and all 4 of them are not
as consistent.
