Erm, scriptindex will look for input on stdin if you don't specify a
"dump" file on the command line.  So you can just remove the
"/dev/fd/0".

You're right, there's a race there currently.  But you're also right in
suggesting that it's easily solved by chdir() to the database directory.
That will also simplify path handling actually.
