I'm not yet convinced that your solution does what I want in a reliable
fashion.

Scanning the directory for new files, as the aforementioned script does. If
you have more than one script doing this at the same time, both may conclude
that a given file is ``available'' and try to act upon it. Inevitably, one of
those scripts will fail. Hence my solution. But maybe I don't quite understand
the problem :-)
(Yes, I know you will say, "Don't run more than one script at a time then.".
But whether this is possible really depends on the application and moreover
seems to be an unecessary restriction.)
