Kenn,
The question I really meant to pose is whether the moisture dynamic in the
wall gets changed due to the slowing of the air movement in the wall caused
by the addition of the cellulose such that it is possible for sufficient
moisture to be brought into the wall and condense and not enough movement
for the wall to dry.  An uninsulated wall has so much air moving through it
that any water vapor that can condense will also be reomoved in a six month
period and the wall will never be wet long enough for it to rot.
