This versions adds two new features to lessfs.
A. Synchronous replication.
Lessfs now supports a master / slave configuration. In this case the master will synchronously replicate the data to the slave. The slave is read-only.
The master will freeze for ever when the slave becomes unreachable. Many options will be added in the future, including maintaining a replication backlog and async replication. The replication feature should be considered alpha code.
B. Background delete.
When enabled lessfs will spawn a background thread that will take care of the truncation/delete task. Lessfs will therefore return immediately after a delete or truncate operation. This is a new feature and is therefore not enabled by default.
