The VectorClock is protected by a global mutex. When possible, it is preferential to avoid unnecessary calls to this global lock. One caller is the Variables::generateRuntimeConstants function which fetches the ClusterTime even though a query may never access $$CLUSTER_TIME. I believe it is possible to analyze the query for $$CLUSTER_TIME usage like $$USER_ROLES is checked for.
