You are absolutely right, I reviewed my explanation, this is simply a
bug what your patch fixes nicely. Just for record, if you switch code
during sleep this code will happily use new versions for F() and G(),
while f() and g() are intact.

	F = fun f/0,
	G = fun() -> f() end,
	io:fwrite("l: ~p ~p ~p ~p~n", [f(), g(), F(), G()]),
	timer:sleep(60000),
	io:fwrite("l: ~p ~p ~p ~p~n", [f(), g(), F(), G()]),

Thanks for the clarification!
Attila
