Comment 7 for bug 1314409

To summarise the conversation I just had on IRC:

 * juju is using separate maas users for each maas environment
 * the oil2 machine "node-9df8a42a-c4cd-11e3-824b-00163efc5068" is also appearing in oil4's status output as pending

The question is, how can the same node seemingly be appearing on both juju environments? MAAS thinks it's allocated to oil2 (I think?)
