* A simple pointer that locks and holds a mutex until destroyed |

* copied it hands off the mutex to the copy and clears it in the original, |
||||
* meaning that the mutex is unlocked when the last LockingPtr<> in a chain |
||||
* of such handoffs is destroyed. If this chain of handoffs "forks" (more than |

* one copy is made) then non-determinism may ensue. |
