you couldn't -) we discussed it last week en-route

there is not much advantage in multiple lua engines because they cannot 
share data (unless we use very inefficient mechanisms) and all action 
with regards to tex takes place in instance 0 anyway

because a directlua call is re-entrant there is not that much need for 
multiple instances any more
