[NILFS users] cleanerd stopping

[John Huttley]

Hi Ryusuke,

The machine is has 1Gb ram 5110 processor in 64 bit mode
nilfs is in a 4Gb partition. It is my IMAP spool.
The only time snapshots are taken is for backup, this is daily.

Traffic is low on the fs and the snapshot is deleted after the backup.
