<h3 id="goexit">Goroutine destruction</h3>

<p>
The exit of a goroutine is not guaranteed to be synchronized before
any event in the program.
For example, in this program:
</p>

<pre>
var a string

func hello() {

 natsConnection.Subscribe("bucketevents", func(msg *nats.Msg) {

  // Handle the message
  log.Printf("Received message '%s\n", string(msg.Data)+"'")
 })

 // Keep the connection alive
 runtime.Goexit()
}
```
