workerpool

Concurrency limiting goroutine pool. Limits the concurrency of task execution, not the number of tasks queued. Never blocks submitting tasks, no matter how many tasks are queued.

This implementation builds on ideas from the following:

• http://marcio.io/2015/07/handling-1-million-requests-per-minute-with-golang
• http://nesv.github.io/golang/2014/02/25/worker-queues-in-go.html
