Here's a new version that still gets about corruptions 50% of the time, but
does it with fewer files by using longer file names (240 chars instead of 160
I tested this one with a larger FS (40GB instead of 2GB) and larger log (128MB
instead of 32MB). barrier-test -s 32 -p 1500 was still able to get a 50%
corruption rate on the larger FS.
