[Simon Küppers <simon.kueppers@xxxxxx>]

I agree with JP, however I see a chance for KiCad, where this feature 
might work better than in other EDA packages.
I think the only way to get this feature to perform well is to use all 
available processor cores.
Maybe it is enough to distribute all the zones to the processor cores. 
However i do not know if the KiCad sources allow this kind of 
multithreading.

Best Regards
