Hi Nick,

I don't understand how this actually works; you're returning an  
address of 0 for the GV instead of a stub, but there's no process by  
which the call to address zero is rewritten to the actual address  
after the pending function is emitted.  Can you explain how this would  
work in non-lazy jitting if function C called A and B which call each  
other?

Thanks,
Nate
