It would be rather interesting to see the results of equivalent tests performed today, with modern systems. For one thing, the possible set of 'funny' characters in file names have expanded quite a bit since 1991, and $DEITY only knows what new and exciting file system bugs have been introduced with the various newer file systems on Linuxes, Solaris and others.
