The usage of fibers in threadpool v12 did not provide any benefit realted to 
invoking tasks recursivly (it is slower because of its syste mcalls). I've 
enabled fiber migration to other worker-threads (stealing) inv v13. But I get 
runtime errors like discussed in the discussions in the mailing list (for 
instance pobs with locked mutexes in fibers). Maybe I've also some 
implementation bugs - the code using fibers is not stable.
I'm open for discussion.
