Yes, that would be exactly the way. All the stack-managing machinery
makes still sense in such an environment. What would have to be modified
is the write-barrier (C_mutate) and copying live stack data into the
secondary heap (which in this case would be managed differently).
Where I see problems, though are data-representation issues...
