If you feel comfortable doing this, please do. The reason I'm calling it 
an abandoned experiment is that unless I'm mistaken, there is nobody 
left in the Squeak community who could fix any issues arising here. That 
means that although we might be able to mechanically pick some fixes 
from Pharo, there is no ownership of the code itself which means that if 
there is ever a real issue we'll be left without help. Which is a risk 
that I'm generally not comfortable in taking and less so if the kernel 
of the system is involved. We need to own that code if we want to 
develop it further.
