Binary Compatible Critical Section Delegation

In high-performance applications, critical sections often become performance bottlenecks due to contention among multiple cores. Critical section delegation mitigates this overhead by consistently executing critical sections on the same core, thereby reducing contention. Traditional delegation techniques, however, typically require manual code refactoring, which limits their practicality and adoption. More recent schemes that integrate with existing lock APIs have lowered this barrier, but delegating unsupported critical sections can still cause undefined behavior, including crashes.
