+        A more comprehensive CV that does not strictly abide by the alternative stricter assumptions.
+        This object depends on the synchronization of primitives within our abstraction layer rather than
+         the OS's implementation of condition variables.
+        In some instances, the cond mutex/var implementations are directly backed by an OS primitive,
+         sometimes they're  reimplemented. In this primitive any locking interface can be used, and an
+         AuThreadPrimitive is used for the sleep operation.
         Note: Missing 'pWaitable's cannnot serve as an `atomic wait for while is [not] value` operation.
               There are no legal use cases for this feature. It's just there.
