> The IO tracing facility introduced with OAK-5655 should also be available during normal
operation. The idea is to log IO reads intercepted via an {{IOMonitor}} instance to a logger.
If {{DEBUG}} logging is not enabled for that logger at the time when the {{FileStore}} is
instantiated, then no tracing would take place.
