Ok, then something like this should do the job:

---

import sys
import os
import unittest
import time
import tempfile
import shutil
from datetime import datetime

import dbus

DS_DBUS_SERVICE = "org.laptop.sugar.DataStore"
DS_DBUS_INTERFACE = "org.laptop.sugar.DataStore"
DS_DBUS_PATH = "/org/laptop/sugar/DataStore"

bus = dbus.SessionBus()
proxy = bus.get_object(DS_DBUS_SERVICE, DS_DBUS_PATH)
data_store = dbus.Interface(proxy, DS_DBUS_INTERFACE)

for i in range(0, 10):
    results, count = data_store.find({}, ['uid'])
    print count
    for props in results:
        props2 = data_store.get_properties(props['uid'])
        data_store.create(props2, '', True)

---

If you run it from an ssh session, you'll need to

export DBUS_SESSION_BUS_ADDRESS=unix:path=/tmp/olpc-session-bus

And if you kill the journal first, it will be much faster because it
won't be burning cpu cycles updating the UI.

Good luck,
