Re: state of the Lua nation on resource cleanup

One answer for coroutines in the scope manager pattern is that one  
needs not just on_exit and on_failure, but also the pair on_yield/ 
on_resume.

One could also treat coroutine death as being signaled with an  
exception before the coroutine actually goes away. Or more generally a  
coroutine with outstanding finalizers is itself a finalizable object  
either via an exception thrown from the yield or simply by running the  
finalizers.

Do upvalues get processed when a coroutine gets collected?
