   …h group-… (#6052)"
   
   This reverts commit 841fa06c7b34916c09df920b7029974a78255cd0.
   
   The reason is that this commit creates problems with ongoing
   put operations during the grace period (very long response
   times) and also, if operations rate is high, it could prevent
   that the gateway sender is stopped.
   
   Put operations can be very slow during the grace period
   because they need to traverse the gateway sender queue
   to find events with the same transactionId. If the queue
   size is big and events are evicted to disk, the time to
   process a request can be unacceptably long.
   At the same time, this can provoke that the gateway sender
   is never stopped because it is blocked trying to get
   a write lock and the lock is held by ongoing operations
   for a long time.
