Do you mean that the cost of the managing interruptible threads is null?
Don't forget that you need to manage with the waiting condition 
variables so that you can interrupt the fiber, which has some cost 
independently of whether you use an atomic or a mutex.

The same argument you are using to support several schedulers should 
apply here, as it is evident to me that the interruption management has 
a performance cost.
