> This class uses synchronization on the queue to limit access to one put at a
> time. Synchronization isn't a fair locking mechanism so threads can be
> blocked trying to add events to the queue while other more recent events get
> the lock and insert their events. This causes inconsistent latency which
> I've observed being as long as 30 seconds, causing client connections to be
> shut down by the ClientHealthMonitor.
