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/executor/scoped_task_executor.cpp:375: MISSING_LOCK 175186 Accessing "this->_inShutdown" without holding lock "mongo::executor::ScopedTaskExecutor::Impl._mutex". Elsewhere, "mongo::executor::ScopedTaskExecutor::Impl._inShutdown" is written to with "Impl._mutex" held 1 out of 1 times.
