The same results have been observed in Japan.  The mud walls breath and
regulate the humidity and don't leave enough condensation for mold. 
This fact was made clear when Japan switched over the the faster and
cheaper, to build with cement, which doesn't breath much at all and mold
problems ensued, whereas the older mud walls did not have this problem.
