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 
chars).

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.
