Maybe it's not required, literally, but in the terms of a common sense,
this is nice to be implemented. In Windows (CreateFiber, SwitchToFiber, ...)
this works nicely. If there's an exit it is used.

I don't understand, why return works as expected, but exception does not.
uc_link is designed for this purpose, isn't it? Maybe exceptions aren't listed 
in standards because ucontext is thought as a C API?

Then there should be some kind of documented workaround, isn't it?
