the command:
rdiff-backup --check-destination-dir /backup/hostname
fails after consuming over 4Gb of real memory (it used zero swap memory). There are about 13 million files (709 Gb) of data.

Here the traceback (verson 1.2.8 on Debian Squeeze):

I think this option should execute using a constant
amount of memory.

I have a user directory which cannot be backup anymore
neither checked because the memory it requires is huge,
so at some time Linux kills the process.
