Detect multithreaded access . This method is called only if detection is enabled . The method ensures that the current thread id matches the saved thread id for this MC . If the MC was just taken out the pool the thread id may not have been recorded yet . In this case we save the current thread id . Otherwise if the thread ids don t match log a message indicating that multithreaded access was detected .
