https://github.com/atemerev/skynet/pull/53

Is there something wrong with this implementation?

"Hope I suck at coroutines, because the results are abysmal.

I get around 63s on my i5 MacBook Air Early 2015. For reference, the go 
version got around 700ms with GOMAXPROCS=4 and 1.7s with GOMAXPROCS=1 on 
this same machine."
