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
/src/mongo/transport/asio/asio_networking_baton.cpp:513: MISSING_LOCK 153320 Accessing "this->this->_inPoll" without holding lock "std::unique_lock<std::mutex>._M_device". Elsewhere, "mongo::transport::AsioNetworkingBaton._inPoll" is written to with "unique_lock._M_device" held 1 out of 2 times (1 of these accesses strongly imply that it is necessary).
