Well, as far as I can tell, site does several things. It calls 
abs__file__ which, afaict, doesn't effect sys.path. Then it calls 
removeduppaths, which walks over sys.path. That means that sys.path has 
already been set by something at that point. So, how/where did sys.path 
get set then? Or is sys.path always empty there at startup and this code 
is just to handle other situations?
