github.com/mixedmessages/taskrunner (go): Package taskrunner provides an API for running concurrent tasks in a promise-like style without having to deal with concurrency directly.  The library provides an interface that must be implemented to run a Task concurrently and a concurrency-safe API for running tasks concurrently without managing the channels, goroutines and waitgroups yourself.
