Thanks for taking the time to write this up.  As far as I can tell, the
looping was actually fixed in an older kernel and I just misread our
version string in your original email.

Yeah, the blogpost says 3.3.7. I did a quick test with 3.7 and was not
able to reproduce it.

I tried with 3.3 and every step between 3.3 and 3.7.  I'm not able to
reproduce the problem, and I did run with Hack=True in the script
(thanks for the flag btw, I really like that).

So, that leaves us with a few possibilities:

1) mount -o seclabel
2) The small size of the device
3) loopback

I ran with a 1GB FS here on 3.3 and wasn't able to trigger things.  But
Pascal, could you please help narrow the problem down?

Ok, I think what was happening on Pascal's machine is that we are
returning -EOVERFLOW and sometimes aborting the transaction (which turns
the FS readonly).

I have that fixed here.  Rename I'm reodering the rename code a little
bit to also handle the case where there are collisions on rename.
