Note that this would somewhat sabotage their usefulness as 
coroutines, depending on how it was implemented. That's not to 
say the idea isn't good (but I'd frame it more like "tasks"; see 
Thread Building Blocks or similar), but fibers/coroutines as they 
stand now are useful so I'd hate to see that capability lost.
