A benign datarace can occur between the array buffer tracker and using an arraybuffer as an asm.js memory. The former reads the {is_shared} bit, which should never change, and the latter writes the {is_asmjs_memory} bit, but no other bits. Since these bits are packed into a single word, TSAN reports a race.
