Static Coroutine in Unity

StaticCoroutine.cs

using UnityEngine;
using System.Collections;

public class StaticCoroutine : MonoBehaviour
{
	private static StaticCoroutine _instance;

	public static void Do(IEnumerator enumerator)
	{
		if (_instance == null)
		{
			var obj			= new GameObject("Static Coroutine Object");
			obj.hideFlags	= HideFlags.HideInHierarchy;
			_instance		= obj.AddComponent<StaticCoroutine>();
		}
		_instance.StartCoroutine(enumerator);
	}

	private void Awake() { _instance = this; }
}

Hi there :)

Can you explain why / when you use a static coroutine?

cheers
