FWIW, this isn't a case I'm worried about. If an embedding program doesn't 
explicitly destroy an interpreter, then its reasonable to assume that the 
interpreter's not dead and shouldn't be cleaned up after--if someone's 
leaking interpreters then, well, they've got bigger problems than the odd 
foreign object. :)
