Heya, Just to keep everyone updated on the matter: It took me longer than expected to get it working (mainly due to the fact that I am running dfly in a VM at the time which does not do make quickworld very quickly.) I think I have a working getcontext now, I will implement setcontext as well and then submit a patch. I would then appreciate testing and someone to look at it whether there is nothing massively broken (I believe get_mcontext was broken as well). Markus
