[PATCH] D45646: [tsan] Zero out the shadow memory for the stack and TLS in ThreadFinish

Let's concentrate on correctness for now.
Shadow memory is not guaranteed to be zeros for new memory. At munmap does not clear it, and probably some other things. Perhaps if you use munmap in test, it will be easier to catch this (e.g. mmap a large chunk of memory, write to it, munmap, create a thread).
