I'd like to point out that Richard is a programmer at CCP and worked on 
game logic among other things. I'm also an employee of CCP and one of 
the people that run the live game cluster.
We run 1 process, running one stackless python thread per CPU and to 
that instance of the interpreter can we map one or more solarsystems, 
based on load of the systems.
