I would have thought so. Once the last reference to the coroutine is lost, the 
entire thing will be garbage collected; code, stack, locals, the lot.

Incidentally, you can *only* do this, with someone else's coroutine if you're 
running --- if it hasn't yielded, then *it* must be running! Remember that 
coroutines aren't threads.

I am curious to know what happens if a coroutine nils out its own last 
reference, though. Does the program counter carry an implicit reference to 
the code its executing? What happens when the coroutine yields?
