OK, here's one... I built a new VM and I can't see the UI process any more in 
the ProcessBrowser.

If I use the Squeak3.0 or 3.1 images with the 2.9 VM (or the older 3.0VM) I 
can see the UI process. If I print ( Processor currentProcess) in a Workspace 
I see (a Process in nextEventFromQueue) or something like that.

With the new VM I don't see the UI process in the Process Browser, and if I 
print (Processor currentProcess) I see (a Process in nil)...

So something in the VM I made made this go away. I suspect that it's the new 
exception handling code, as that seems to be the big change to interp.c .
