+/// Without this option, Poco library will restart recv after EINTR,
+/// but it doesn't update socket receive timeout that leads to infinite wait
+/// when query profiler is activated. The issue persisted in delayed_replica_failover
+/// integration test after we enabled query profiler by default.
