I can't think of a reason media would be much slower in complex CSG's, 
and I haven't experienced this problem myself...

The new noise function is easier to use(because it stays within the 
expected range), and can already be used to simulate the old one. You 
could even make a function which behaves like the old one, hard-coding 
it into the program isn't necessary. Or you could just adjust the 
color_maps to simulate the "plateaus" at each end of the map.
It will produce clouds which are just as good as the old noise, just not 
with the exact same code.
