    Description

      We can use relaxed ordering for TrackingAllocatorStats::bytesAllocated since this only requires atomicity. Reading the value to report memory usage may return a slightly stale value, which is fine.

      Additionally, we can stripe bytesAllocated to avoid hitting the same cache lines
