-               This example illustrates a self-satisfying cycle involving
-               synchronization.  A failed synchronization creates the store that
-               causes the synchronization to fail.
-
-               The C++11 memory model nominally allows r1=0, r2=1, r3=5.
-
-               This example is insane, we don't support that behavior.
