See racer test at

It does the above, but a bunch more things and is a truly pathalogical
test script that does lots of "stupid user tricks", unlike normal tests
which are only doing operations that expect to be successful.

PS - during the test run "rm" is known to segfault after hitting
an internal assertion, nobody is sure why.
PPS- I don't know who wrote this program, it was originally posted by
someone not the author to linux-fsdevel or something.

Thanks. That's a nice little test suite.
