Hi Michael,

how would you execute [ some long computation ] on another processor or  
another computer.

On another processor, Squeak does't work because its VM is neither  
reentrant nor multiprocessing-capable (sorry for using terms which are >  
30 years old ;-)

So it would be interesting to learn how you plan to offload [ some long  
computation ] to another computer (or, FWIW, to another process running on  
the same computer).
