It's with the 2.6.27-rc8 based ptools tree. Prior to checking
in these patches:

Can't lock inodes in radix tree preload region
stop using xfs_itobp in xfs_bulkstat
free partially initialized inodes using destroy_inode

I was able to stress a system for about 4 hours before it ran out
of memory. Now I hit the deadlock within a few minutes. I need
to roll back to find which patch changed the behaviour.
