    Ftpd doesn't do any file locking at all. What makes you think it's related
    to this?

    What criteria does the script use to determine if the upload is complete?
    Ftpd creates the file as soon as the upload starts, and doesn't provide any
    way to tell when it's done.

    The usual recommendation is to upload the file to a temporary name, and
    then have the client rename it when it's done. That way, the file that the
    script looks for won't exist at all until the upload is complete.
