On casual glance, it looks like a test meant to test the end of 32-bit offsets, built to test a specific ext4 case, and it happened to strafe XFS on 32-bit in the process. It is unknown to me whether a script with 64-bit version of the numbers would have a bad effect.

Oops, that was supposed to be "kernel 3.9-rc4." Sorry.

Runs fine on all my 64 bit machines. I quickly ran a test using 3.9.0-rc1+ on a 32 bit machine. I am seeing the same xfs_io 100% CPU usage.

Looks 32 bit specific.
