 ## Examples  
  The following is an example of using SpinWait in a simple lock-free stack implementation. (This is just an example. If an efficient, thread-safe stack is needed, consider using ConcurrentStack.)

- `Node node = new Node { Value = item }, head;`  
-  
- `while (true)`

- `{`  
-  
- `head = m_head;`  
-  
- `node.Next = head;`  
-  
- `if (Interlocked.CompareExchange(ref m_head, node, head) == head) break;`

- `spin.SpinOnce();`

- `}`
