I am forwarding a message from David (Thanks a lot to him) who pointed
that SystemTracer2 should be run with a non-cog VM otherwize, the
generated image is not usable.
Does someone know why?

Actually, I think I just spotted the problem. If I use an interpreter
VM to run the system tracer, then load the cloned image with an interpreter
VM, then save the cloned image, then run it under Cog, it works.
If I use Cog to do the system tracing, the cloned image does not work.
If I use the interpreter VM to trace the image, then run the cloned
image under Cog, it does not work.
If I run the same cloned image on an interpreter VM, it works.
After the cloned image has been saved from an interpreter VM, it
can be used with Cog.
I do not know the reason for this, but that is what I am seeing.
I am using Linux, but on a Mac you can probably use Ian's unix VM
for Mac from http://squeakvm.org/unix/ and see if you get the same
