I don't quite see how you plan to make this work without tracking 
dirty objects, which has a performance/storage penalty.

Fiber1 has memory chunk A

Fiber2 has memory chunks A, B

You confirm that sleeping Fiber1 does not have access to B

Fiber2 sets A.next = B

At this point, you assume wrongly that Fiber1 does not have 
access to B?
