getTaskDetails() intermittently fails with connect() timed out

I am seeing intermittent errors using IronWorker (version 1.4.4) and calling:

```
$task_details = $worker->getTaskDetails($argv[6]);
```

The error is: 

```
Failed to retrieve IronWorker task '5596c9df1aef88000c018984'' details. http error: 0 | connect() timed out!
```

This is an internal error inside of Iron.io, please investigate and report back.
