Spawning fiber is expensive (but not so expensive as spawning 
thread, of course), but switching is fast.

Thus, you can spawn and pause "workers" fibers for avaiting of 
jobs.
(Probably, this behaviour is already implemented in number of 
libraries and it isn't actually need to implement another one.)
