  I still don't understand.  If the base clock sends
- - - - - - - - - - - - - - - - -    and a divided by 3 clock then sends
---   ---   ---   ---   ---   ---    (where "---" is actually a solid line)
the only opportunity I see for noise is when the slower clock's transition
slightly lags the other. But that lag is less than one tick of the fast
clock, and thus could only be noticed if you had a measuring instrument
with a resolution faster than the base clock - which is supposed to be
the fastest clock in the system.
