If another thread reuses our slot before we intentionally trigger the UB we want to detect, we may find dealloc_count reset so we do not hit the UseAfterFree case above. We don't synchronize allocators with signal handlers, so mprotect-then-reset may still end up racing if the segfaulting thread is arbitrarily delayed. PiperOrigin-RevId: 944768039
