https://github.com/Jeffail/tunnyTunny is a Golang library for spawning and managing a goroutine pool, allowing you to limit workcoming from any number of goroutines with a synchronous API.A fixed goroutine pool is helpful when you have work coming from an arbitrary number of asynchronous sources,but a limited capacity for parallel processing.
