I can only second that. I find polishing to be mostly useful within a 
subsystem when I have time to do final tweaks but most parts of the 
system are not in that shape and actually require more drastic changes.

Actually, it is more worthwhile to think about how the globals interact 
than merely replace them. If you look at what David and I have done with 
  Projects you get the idea - define an interface that provides a 
natural bottleneck for the context of the operation and vector it 
through this.

Most of these could (and probably should) be vectored through Project 
current (i.e., Project current display/sensor/world/sources) and it 
would make some excellent sense because much of it is already project 
bound. That's the kind of refactoring that is both useful and (when 
complete) quite rewarding as it allows us to unload things that were 
previously unloadable.
