I was wondering, though, whether the parent directory would
be non-delete-able while find has the directory open for scanning.
If the application in question creates and deletes the parent
directory, as well as the leaf file, then things would be left
around unexpectedly.

So would use of find trigger a virus scanner, which in turn might
hold on to the file and prevent its deletion?
