I don't understand. There is no 'problem' to workaround. This is by 
design. You're right, the GC has to reclaim your deleted files before it 
release the space to the filesystem. If you remove all your checkpoints 
and wait for your 'protection_period' interval you should see you space 
reappear. The whole idea or nilfs is that you could do a 'rm -rf *' and 
be left with no files, but still recover all your files from a 
checkpoint that happened for you automatically a few seconds ago.
