The emulator would be a separate process, loading itself, with the nested
instance having its own resources. In an arbitrary-context instrumentation
framework, you've got one instance of this thing in the one kernel, with
finite resources and you can't arbitrarily allocate more as you go.
You can allocate from the stack and say 'no stack left for probing' if
you are out of stack. What's the stupid problem with that?
