For the fixing later:
PC: 
CPU: AMD Athlon XP 1,6+
RAM: 512 MB DDR RAM
Nilfs2 Version (Module and Tools): 2.0.2
Partition: 251 GB dmcrypt
Files: 2x approx. 100 GB created with dd if=/dev/zero of=bigfile, to
erase the old content on the cryptopartition (the zeros are written
encrypted to the real partition)

Problem while deleting them as described:

Now i'm using the same setup with a nilfs2 with "normal" files on it,
filled to 11 GB (df -h), without any further problems. 

I do not want to
experiment in a way, that the partition needs to be reformatted later
again :/.
