That's a rather long list of primitives.
Most images only use the resolver primitives, and optionally the TCP primitives. If it's a Squeak image and useOldNetwork is enabled, then you don't have to implement the new network primitives either.
Right. Worry not. I'm implementing as simulation proceeds, so I'll implement the minimum necessary. I realise I may be able to get away with updating from a local repository, but I'm having fun implementing the SocketPluginSimulator so for now I'll continue on this route.
