Hi again Swabby,
what I wonder... you use a mutex (e.g. CCriticalSection CGnuControl::m_NodeAccess) only on write access to your socket lists (adding/removing nodes), but not also on read access (broadcasting packets). I don't think that std::vector<> is thread safe. I did cross check with Mutella, and Max does use a Mutex on read and write access - which is what i do usually too.

I would expect unexpectable behaviours in Gnucleus - or did I overprotect my code?
