new WAL arrives via streaming replication. This reduces the latency, and also allows us to use a longer polling interval, which is good for energy efficiency. We still need to poll to check for the appearance of a trigger file, but the interval is now 5 seconds (instead of 100ms), like when waiting for a new WAL segment to appear in WAL archive.
