Hi Rob.

I think that many other people would be interested in this. I suggest making
stage 3 here a separate project in its own right. If it is stable and works
well, I could see it becoming the official Squeak VM. Also keep integration
with Exupery in mind.

I also recommend starting this project by changing the behaviour of
ProcessorScheduler to behave in the same way as the multi-threaded VM.
Currently code can assume that a lower priority process won't run while a
higher priority process is busy; this assumption would no longer exist in
the multi-threaded VM. This would be a reasonably simple change and I
believe this may pick up several concurrency issues in the image.

Gulik.
