Oh, and I've attached the current version of my test program if anyone is 
interested.

It spawns 8 child processes which repeatedly create up to 1,000,000 files 
each, stat up to 1,000,000 (probably) non-existant files, and then unlink the 
files they created.

It also spawns another 4 processes which iterate over all of the directory 
entries using readdir(). For each file it encounters, it has an equal 
probability of renaming it, unlinking it, or truncating it to a random 
length.

It can corrupt my loopback test filesystems in under 5 minutes. Note that it 
will completely destroy any data in its working directory, however.
