I did some further investigation into the problem, and I have
determined the problematic directory (by seeing where `ls -R` hangs).
If I skip the corrupt directory, everything works properly, but
attempting to list its contents causes the entire volume to stop
responding.
At this point I'd like to simply unlink the corrupt directory (without
enumerating it). Is that possible, or should I just image the volume
minus the corrupt directory and recreate my fs?
