+    /** Condition variable
+
+       A condition variable is essentially an object that is initially
+       cleared which a thread waits on until it is "set". It allows a
+       thread to synchronize execution by allowing other threads to wait
+       for the condition to change before that thread then continues
+       execution.
+
+       @deprecated use C++11's std::condition_variable instead
+            for a more robust and helpful condition.
+
+       @attention Warning: the Condition abstraction is inadequate for
+            any situation where there may be multiple threads setting,
+            waiting, and resetting the same condition. It can only be
+            used to synchronise interactions between two threads
+            cf. lost wakeups in http://www.cs.wustl.edu/~schmidt/win32-cv-1.html
