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.
