+        Code that produces query IDs and updates the value of the
+        <literal role="statvar">Threads_running</literal> status
+        variable no longer acquires a global lock which also protects
+        the list of all connections. Instead, it relies on atomic
+        increment and decrement instructions. This improves scalability
+        and to a certain extent alleviates the problem described in
+        Bug#11751904.
