```
+    if (!(frequency.QuadPart = ReadAcquire64( &freq_cache )))
+    {
+        QueryPerformanceFrequency( &frequency );
+        WriteRelease64( &freq_cache, frequency.QuadPart );
+    }
     QueryPerformanceCounter( &counter );
```

Why do we need acquire/release here? Where is the barrier pair?

```
-static inline int g_atomic_int_get( int *ptr ) { return ReadAcquire( (LONG *)ptr ); }
+static inline int g_atomic_int_get( int *ptr ) { int value = ReadNoFence( (LONG *)ptr ); MemoryBarrier(); return value; }
```

Why?
