Illuminating synchronization edges for ThreadSanitizer

Sanitizers are powerful development tools which complement debuggers and fuzzing. I typically have at least one sanitizer active during development. They’re particularly useful during code review, where they can identify issues before I’ve even begun examining the code carefully — sometimes in mere minutes under fuzzing. Accordingly, it’s a good idea to have your own code in good agreement with sanitizers before review. For ThreadSanitizer (TSan), that means dealing with false positives in progr...
