That seems like a bad idea: a value that is accessed via multiple 
coroutines (or passed via resume/yield, or in a function that is called 
from multiple coroutines) would get/loose its metatable depending on 
where it is used.

And then `io.open` wouldn't find its metatable when called from within a 
coroutine, C libraries would be loaded and gc'd multiple times, etc. ...
