More info, tested current linus 2.6.38git including "xfs: Reduce OOM kill 
problems under heavy load V2" patchset but the result wasn't much better:

3549921 3549921 100%    1.06K 132791       30   4249312K xfs_inode
(from slabtop), machine became unresponsible and rebooted.

I wonder if 8GB of ram would be enough for this 800GB fs to mount.
