An object of type `hazard_pointer` is either empty or *owns* a hazard
|
| 23 |
+
pointer. Each hazard pointer is owned by exactly one object of type
|
| 24 |
+
`hazard_pointer`.
|
| 25 |
+
|
| 26 |
+
[*Note 1*: An empty `hazard_pointer` object is different from a
|
| 27 |
+
`hazard_pointer` object that owns an unassociated hazard pointer. An
|
| 28 |
+
empty `hazard_pointer` object does not own any hazard
|
| 29 |
+
pointers. — *end note*]
