end of the story
so i don't know if this helps a bit more, it still seems to be in the underlying system a bit
what i saw and found disturbing though, was the use of malloc together with the obj-c memory management (ofwhich i know nothing)
is it maybe possible, that both don't mix so well, so there has to be another allocation method used in interfacing c code?
i'll try another round
). It looks like we are deep in the AI - I have no idea whether all these stacks are helping. Let me know if you want me to run with some debug code - normally I run at about 40% cpu usage in oolite so I have plenty of CPU headroom still.
