+
+ Implement the alwaysRunsAtBackgroundPriority WK2 setting using thread QoS.
+ <https://webkit.org/b/167387>
+ <rdar://problem/29711409>
+
+ Reviewed by Antti Koivisto.
+
+ Add a new mechanism for overriding the max thread QoS level globally:
+
+ void setGlobalMaxQOSClass(qos_class_t)
+ qos_class_t adjustedQOSClass(qos_class_t)
+
+ The QoS cap applies to all newly created threads, threads that try to override
+ their QoS class manually, and also passed down to bmalloc.
