Domains are still experimental (and doesn't have support in browser). Also, I believe that if you decide to use the dark side of the Force - it's better to use it at the full potential with the Fibers. > Reads much nicer even if it is more lines of code. Nicer? :) Don't know, for me the nice version is the synchronous one (with generators, code generators, yields, fibers etc.), but I believe the version with fork is still shorter and simpler.
