                Concurrency in golang and a mini Load-balancer
              
          
    INTRO

Concurrency is a domain I have wanted to explore for a long time because the locks and the race conditions have always intimidated me. I recall somebody suggesting concurrency patterns in golang because they said "you share the data and not the variables".
Amused by that, I searched for "concurrency in golang" and bumped into this awesome slide by Rob Pike: https://talks.golang.org/2012/waza.slide#1 which does a great job of explaining channels, concurrency patterns and a mini-architecture of load-balancer (also explains the above one-liner).
Let's dig in:
Goroutines

	"flag"
	"fmt"
	"log"
	"net/http"
	"os"
	"os/signal"
