sorry - at the end of the function there is a close() method to a
file, after the thread passes the modifications:

    try:
        os.remove(self.lockfile)
    except:
        syslog.syslog(syslog.LOG_DEBUG, "Sync error: " + str(sys.exc_info()[1]))

And I think, the "(deleted)" info near the filename in proc/PID/fd
means the lockfile had been deleted.

sounds good, thanks - what's the minimal version of Python? I've
only 2.5 on that server...
