Error is accompanied by a detailed error being sent to the writer's monitor.

Consumer_left is returned when the consumer leaves (see consumer_left) and raise_when_consumer_leaves is set to false. If that flag is set to true, then you get an Error instead.

Force_closed is returned when Writer.close is forced before all data is flushed (see ?force_close).

The time just after the write() system call returned or the time flushed_* was called if all the writes were already flushed by then.
