Hi Rico,
there is more going on than that. I just disabled all those locks for testing and nothing changes (funnily it's not even crashing). I will try to have a look. Rewriting everything so each thread get's thread-specific datastructures might be more than I am ready to do though. On the other hand, sounds like a good plan for Christmas.
