-// Note on use of Broker::getTimer() rather than getClusterTime in broker code.
-// The following uses of getTimer() are cluster safe:
-//
-// LinkRegistry: maintenance visits in timer can call Bridge::create/cancel
-// but these don't modify any management state.
-//
-// broker::Connection:
-// - Heartbeats use ClusterOrderOutput to ensure consistency
-// - timeout: aborts connection in timer, cluster does an orderly connection close.
-//
-// SessionState: scheduledCredit - uses ClusterOrderProxy
-// Broker::queueCleaner: cluster implements ExpiryPolicy for consistent expiry.
-//
-// Broker::dtxManager: dtx disabled with cluster.
-//
-// requestIOProcessing: called in doOutput.
