-------------------------------------
This is especially true now that the Logger uses multiple disks (1.4).

> If the disk is full for a Logger it will kill itself quickly. Instead we should have it fail into a 'read-only' mode, that way tservers can still do log recovery based on the data it has. It needs to be treated in such a way that tservers won't rely on it to log their new data, but can be used to recover older data.
