Darn.  Well, that was a bit of a long-shot, but worth a try.

Oops.  My fault.  I thought the `stat' command had an option to
list all files in a given directory.  I guess you'd have to combine
it with `find' to do that.

Perhaps, but as a general rule we'd like our system utilities to
at least *work* in extreme situations.  This is something I'd
love to dig into if I had the time, but I'm not sure I have the
time right now.
