Hi Markus,
I'm interested as to what your log file looks like and how you discern 
which percentage value is coming from which process. Are they not all 
mixed together anyway? I was thinking perhaps you could filter the stderr 
of each GRASS module through a short C program that could strip the 
backspace characters and print the name of the module with it's progress 
value on a new line every time there is a new percentage point? Or is the 
problem not complicated enough to need such a solution?
