Some of the ReiserFS developers gave a similar reaction to some of my bug 
reports.  ReiserFS wasn't the most robust filesystem.

I think that it should be EXECTED that a kernel will have to occasionally deal 
with filesystem images that are created by hostile parties.  Userspace crash 
and kernel freeze is not a suitable way of dealing with it.
