Well yes, we *are* talking about Smalltalk here, after all.

I think BHH kept the bytecodes all in the CM but used a Closure object  
in place of using the copyBlock bytecode and then a blockcontext was  
created each time the closure was evaluated. But it is a very long  
time since I last did any active development of that VM, most likely  
1991. Too long to remember details!
