+ <para>
+ 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.
