Michael, this CL has caused Windows DrMemory bots to report megatons of memory
leaks:

Um, sorry, these aren't leaks, but "prefetching of unaddressable memory".

Thanks for the info. This is most probably caused by r14280 on V8 bleeding edge.
Yes, it is a prefetch instruction that is causing this warning. We will take a
look.
