ext4 fs corruption at power cut

I'm using an Ubuntu-13.10 VM for this testing. Kernel 4.0.0-rc3 compiled from git and e2fsprogs 1.42.12.
The steps I run:
 # mkfs.ext4 /dev/sdb1
 # mount -t ext4 -o defaults,barrier=1,noatime /dev/sdb1 /mnt
 # fsstress -w -X -d /mnt/fsstress -l 0 -n 100 -p 100 -s urandom
Let it run for 10 sec and then poweroff the virtual machine:
 $ vboxmanage controlvm Ubuntu-13.10-server poweroff
After reboot, I run:
 # fsck.ext4 -vpf /dev/sdb1
This fails with exit code 4, 2 out of 10 runs. The fail log is attached.
