Let me see if I understand your problem. You are pickling a dictionary and
finding that it will not work unless there already is an existing
dictionary for your pickled dictionary to write over. Otherwise, there is
either no write at all or the write is followed by a delete.  Is that a
reasonable definition of your current problem?
