If nilfs_cleanerd is shut down, then the filesystem will fill up until
there's no room for more data. When you delete data, only the
nilfs_cleanerd can reclaim the space, which is why you set up a
protection_period, deleted data will never be overwritten unless
reclaimed by the cleanerd.
Here is a program I made to represent the disk in a graphical form,
you'll see the cleanerd in action:

You need python-2.4+ with pygtk and nilfs-utils to run the program.
