      Data race condition

      The value of the shared data will be determined by the interleaving of thread execution. Thread shared data is accessed without holding an appropriate lock, possibly causing a race condition

Elsewhere, "mongo::admission::RateLimiter::RateLimiterPrivate.tokenBucket" is written to with "WriteRarelyRWMutex._writeMutex" held 2 out of 2 times.
