Remarks
This intrinsic is not atomic because it is implemented as two separate locked instructions. An atomic 64-bit read that occurs on another thread during the execution of this intrinsic could result in an inconsistent value being read.
This function behaves as a read-write barrier. For more information, see _ReadWriteBarrier.
